CVE Details

Release Date:

2007-10-30

Description

Integer signedness error in the NE2000 emulator in QEMU 0.8.2, as used in Xen and possibly other products, allows local users to trigger a heap-based buffer overflow via certain register values that bypass sanity checks, aka QEMU NE2000 receive integer signedness error. NOTE: this identifier was inadvertently used by some sources to cover multiple issues that were labeled NE2000 network driver and the socket code, but separate identifiers have been created for the individual vulnerabilities since there are sometimes different fixes; see CVE-2007-5729 and CVE-2007-5730. Heap-based buffer overflow in QEMU 0.8.2, as used in Xen and possibly other products, allows local users to execute arbitrary code via crafted data in the net socket listen option, aka QEMU net socket heap overflow. NOTE: some sources have used CVE-2007-1321 to refer to this issue as part of NE2000 network driver and the socket code, but this is the correct identifier for the individual net socket listen vulnerability.
