Ubuntu 10.04 LTS / 12.04 LTS / 13.10 / 14.04 LTS : dpkg vulnerabilities (USN-2242-1)
Medium Nessus Plugin ID 74464
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionIt was discovered that dpkg incorrectly handled certain patches when unpacking source packages. If a user or an automated system were tricked into unpacking a specially crafted source package, a remote attacker could modify files outside the target unpack directory, leading to a denial of service or potentially gaining access to the system.
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected dpkg-dev and / or libdpkg-perl packages.
