CVE-2008-3834

CVE Details

Release Date:	2008-10-07
Impact:	Moderate	What is this?

Description

The dbus_signature_validate function in the D-bus library (libdbus) before 1.2.4 allows remote attackers to cause a denial of service (application abort) via a message containing a malformed signature, which triggers a failed assertion error. The _dbus_validate_signature_with_reason function (dbus-marshal-validate.c) in D-Bus (aka DBus) before 1.2.14 uses incorrect logic to validate a basic type, which allows remote attackers to spoof a signature via a crafted key. NOTE: this is due to an incorrect fix for CVE-2008-3834.
