Ubuntu 10.04 LTS / 12.04 LTS / 14.04 LTS / 14.10 : dpkg vulnerability (USN-2566-1)

Medium Nessus Plugin ID 82697


The remote Ubuntu host is missing one or more security-related patches.


Jann Horn discovered that dpkg incorrectly validated signatures when extracting local source packages. If a user or an automated system were tricked into unpacking a specially crafted source package, a remote attacker could bypass signature verification checks.

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.


Update the affected dpkg-dev and / or libdpkg-perl packages.
