Synopsis
CVE-2024-0727Issue summary: Processing a maliciously formatted PKCS12 file may lead OpenSSL\nto crash leading to a potential Denial of Service attack\nImpact summary: Applications loading files in the PKCS12 format from untrusted\nsources might terminate abruptly.\nA file in PKCS12 format can contain certificates and keys and may come from an\nuntrusted source. The PKCS12 specification allows certain fields to be NULL, but\nOpenSSL does not correctly check for this case. This can lead to a NULL pointer\ndereference that results in OpenSSL crashing. If an application processes PKCS12\nfiles from an untrusted source using the OpenSSL APIs then that application will\nbe vulnerable to this issue.\nOpenSSL APIs that are vulnerable to this are: PKCS12_parse(),\nPKCS12_unpack_p7data(), PKCS12_unpack_p7encdata(), PKCS12_unpack_authsafes()\nand PKCS12_newpass().\nWe have also fixed a similar issue in SMIME_write_PKCS7(). However since this\nfunction is related to writing data we do not consider it security significant.\nThe FIPS modules in 3.2, 3.1 and 3.0 are not affected by this issue.2024-01-22
CVE-2024-0690An information disclosure flaw was found in ansible-core due to a failure to respect the ANSIBLE_NO_LOG configuration in some scenarios. Information is still included in the output in certain tasks, such as loop items. Depending on the task, this issue may include sensitive information, such as decrypted secret values.2024-01-18
CVE-2024-0646An out-of-bounds memory write flaw was found in the Linux kernel's Transport Layer Security functionality in how a user calls a function splice with a ktls socket as the destination. This flaw allows a local user to crash or potentially escalate their privileges on the system.2023-12-07
CVE-2024-0607A flaw was found in the Netfilter subsystem in the Linux kernel. The issue is in the nft_byteorder_eval() function, where the code iterates through a loop and writes to the `dst` array. On each iteration, 8 bytes are written, but `dst` is an array of u32, so each element only has space for 4 bytes. That means every iteration overwrites part of the previous element corrupting this array of u32. This flaw allows a local user to cause a denial of service or potentially break NetFilter functionality.2024-01-16
CVE-2024-0567A vulnerability was found in GnuTLS, where a cockpit (which uses gnuTLS) rejects a certificate chain with distributed trust. This issue occurs when validating a certificate chain with cockpit-certificate-ensure. This flaw allows an unauthenticated, remote client or attacker to initiate a denial of service attack.2024-01-16
CVE-2024-0565An out-of-bounds memory read flaw was found in receive_encrypted_standard in fs/smb/client/smb2ops.c in the SMB Client sub-component in the Linux Kernel. This issue occurs due to integer underflow on the memcpy length, leading to a denial of service.2023-12-18
CVE-2024-0553A vulnerability was found in GnuTLS. The response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from the response times of ciphertexts with correct PKCS#1 v1.5 padding. This issue may allow a remote attacker to perform a timing side-channel attack in the RSA-PSK key exchange, potentially leading to the leakage of sensitive data. CVE-2024-0553 is designated as an incomplete resolution for CVE-2023-5981.2024-01-16
CVE-2024-0409A flaw was found in the X.Org server. The cursor code in both Xephyr and Xwayland uses the wrong type of private at creation. It uses the cursor bits type with the cursor as private, and when initiating the cursor, that overwrites the XSELINUX context.2024-01-16
CVE-2024-0408A flaw was found in the X.Org server. The GLX PBuffer code does not call the XACE hook when creating the buffer, leaving it unlabeled. When the client issues another request to access that resource (as with a GetGeometry) or when it creates another resource that needs to access that buffer, such as a GC, the XSELINUX code will try to use an object that was never labeled and crash because the SID is NULL.2024-01-16
CVE-2024-0340A vulnerability was found in vhost_new_msg in drivers/vhost/vhost.c in the Linux kernel, which does not properly initialize memory in messages passed between virtual guests and the host operating system in the vhost/vhost.c:vhost_new_msg() function. This issue can allow local privileged users to read some kernel memory contents when reading from the /dev/vhost-net device file.2023-05-22
CVE-2024-0229An out-of-bounds memory access flaw was found in the X.Org server. This issue can be triggered when a device frozen by a sync grab is reattached to a different master device. This issue may lead to an application crash, local privilege escalation (if the server runs with extended privileges), or remote code execution in SSH X11 forwarding environments.2024-01-16
CVE-2024-0193A use-after-free flaw was found in the netfilter subsystem of the Linux kernel. If the catchall element is garbage-collected when the pipapo set is removed, the element can be deactivated twice. This can cause a use-after-free issue on an NFT_CHAIN object or NFT_OBJECT object, allowing a local unprivileged user with CAP_NET_ADMIN capability to escalate their privileges on the system.2024-01-02
CVE-2024-0057A security feature bypass vulnerability exists when Microsoft .NET Framework-based applications use X.509 chain building APIs but do not completely validate the X.509 certificate due to a logic flaw. An attacker could present an arbitrary untrusted certificate with malformed signatures, triggering a bug in the framework. The framework will correctly report that X.509 chain building failed, but it will return an incorrect reason code for the failure. Applications which utilize this reason code to make their own chain building trust decisions may inadvertently treat this scenario as a successful chain build. This could allow an adversary to subvert the app's typical authentication logic.2024-01-09
CVE-2024-0056A vulnerability was found in the .NET Framework. This vulnerability exists in the Microsoft.Data.SqlClient and System.Data.SqlClient SQL Data provider where an attackercan perform an AiTM (adversary-in-the-middle) attack between the SQL client and the SQL server. This may allow the attacker to steal authentication credentials intended for the database server, even if the connection is established over an encrypted channel like TLS.2024-01-09
CVE-2023-7192A memory leak problem was found in ctnetlink_create_conntrack in net/netfilter/nf_conntrack_netlink.c in the Linux Kernel. This issue may allow a local attacker with CAP_NET_ADMIN privileges to cause a denial of service (DoS) attack due to a refcount overflow.2023-02-10
CVE-2023-7104A vulnerability was found in SQLite3. This issue affects the sessionReadRecord function of the ext/session/sqlite3session.c function in the make alltest Handler component. Manipulation may cause a heap-based buffer overflow to occur.2023-12-29
CVE-2023-7008A vulnerability was found in systemd-resolved. This issue may allow systemd-resolved to accept records of DNSSEC-signed domains even when they have no signature, allowing man-in-the-middles (or the upstream DNS resolver) to manipulate records.2022-12-08
CVE-2023-6932A use-after-free vulnerability in the Linux kernel's ipv4: igmp component can be exploited to achieve local privilege escalation.\nA race condition can be exploited to cause a timer be mistakenly registered on a RCU read locked object which is freed by another thread.\nWe recommend upgrading past commit e2b706c691905fe78468c361aaabc719d0a496f1.2023-12-19
CVE-2023-6931A heap out-of-bounds write vulnerability in the Linux kernel's Performance Events system component can be exploited to achieve local privilege escalation.\nA perf_event's read_size can overflow, leading to an heap out-of-bounds increment or write in perf_read_group().\nWe recommend upgrading past commit 382c27f4ed28f803b1f1473ac2d8db0afc795a1b.2023-11-29
CVE-2023-6918A flaw was found in the libssh implements abstract layer for message digest (MD) operations implemented by different supported crypto backends. The return values from these were not properly checked, which could cause low-memory situations failures, NULL dereferences, crashes, or usage of the uninitialized memory as an input for the KDF. In this case, non-matching keys will result in decryption/integrity failures, terminating the connection.2023-12-18
CVE-2023-6917A vulnerability has been identified in the Performance Co-Pilot (PCP) package, stemming from the mixed privilege levels utilized by systemd services associated with PCP. While certain services operate within the confines of limited PCP user/group privileges, others are granted full root privileges. This disparity in privilege levels poses a risk when privileged root processes interact with directories or directory trees owned by unprivileged PCP users. Specifically, this vulnerability may lead to the compromise of PCP user isolation and facilitate local PCP-to-root exploits, particularly through symlink attacks. These vulnerabilities underscore the importance of maintaining robust privilege separation mechanisms within PCP to mitigate the potential for unauthorized privilege escalation.2024-02-15
CVE-2023-6915A Null pointer dereference problem was found in ida_free in lib/idr.c in the Linux Kernel. This issue may allow an attacker using this library to cause a denial of service problem due to a missing check at a function return.2024-01-15
CVE-2023-6867The timing of a button click causing a popup to disappear was approximately the same length as the anti-clickjacking delay on permission prompts.

CVE-2023-6817A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. The function nft_pipapo_walk did not skip inactive elements during set walk which could lead double deactivations of PIPAPO (Pile Packet Policies) elements, leading to use-after-free. We recommend upgrading past commit 317eb9685095678f2c9f5a8189de698c5354316a.2023-12-18
CVE-2023-6816A flaw was found in X.Org server. Both DeviceFocusEvent and the XIQueryPointer reply contain a bit for each logical button currently down. Buttons can be arbitrarily mapped to any value up to 255, but the X.Org Server was only allocating space for the device's particular number of buttons, leading to a heap overflow if a bigger value was used.2024-01-16
CVE-2023-6710A flaw was found in the mod_proxy_cluster in the Apache server. This issue may allow a malicious user to add a script in the 'alias' parameter in the URL to trigger the stored cross-site scripting (XSS) vulnerability. By adding a script on the alias parameter on the URL, it adds a new virtual host and adds the script to the cluster-manager page.2023-12-12
CVE-2023-6693A stack based buffer overflow was found in the virtio-net device of QEMU. This issue occurs when flushing TX in the virtio_net_flush_tx function if guest features VIRTIO_NET_F_HASH_REPORT, VIRTIO_F_VERSION_1 and VIRTIO_NET_F_MRG_RXBUF are enabled. This could allow a malicious user to overwrite local variables allocated on the stack. Specifically, the `out_sg` variable could be used to read a part of process memory and send it to the wire, causing an information leak.2024-01-02
CVE-2023-6683A flaw was found in the QEMU built-in VNC server while processing ClientCutText messages. The qemu_clipboard_request() function can be reached before vnc_server_cut_text_caps() was called and had the chance to initialize the clipboard peer, leading to a NULL pointer dereference. This could allow a malicious authenticated VNC client to crash QEMU and trigger a denial of service.2024-01-12

CVE-2023-6531A use-after-free flaw was found in the Linux Kernel due to a race problem in the unix garbage collector's deletion of SKB races with unix_stream_read_generic() on the socket that the SKB is queued on.2023-12-06
CVE-2023-6516To keep its cache database efficient, `named` running as a recursive resolver occasionally attempts to clean up the database. It uses several methods, including some that are asynchronous: a small chunk of memory pointing to the cache element that can be cleaned up is first allocated and then queued for later processing. It was discovered that if the resolver is continuously processing query patterns triggering this type of cache-database maintenance, `named` may not be able to handle the cleanup events in a timely manner. This in turn enables the list of queued cleanup events to grow infinitely large over time, allowing the configured `max-cache-size` limit to be significantly exceeded. This issue affects BIND 9 versions 9.16.0 through 9.16.45 and 9.16.8-S1 through 9.16.45-S1.2024-02-13
CVE-2023-6478A flaw was found in xorg-server. A specially crafted request to RRChangeProviderProperty or RRChangeOutputProperty can trigger an integer overflow which may lead to a disclosure of sensitive information.2023-12-13
CVE-2023-6377A flaw was found in xorg-server. Querying or changing XKB button actions such as moving from a touchpad to a mouse can result in out-of-bounds memory reads and writes. This may allow local privilege escalation or possible remote code execution in cases where X11 forwarding is involved.2023-12-13
CVE-2023-6356A flaw was found in the Linux kernel's NVMe driver. This issue may allow an unauthenticated malicious actor to send a set of crafted TCP packages when using NVMe over TCP, leading the NVMe driver to a NULL pointer dereference in the NVMe driver and causing kernel panic and a denial of service.2023-12-11
