Details

USN-2183-1 fixed a vulnerability in dpkg. Javier Serrano Polo discovered
that the fix introduced a vulnerability in releases with an older version
of the patch utility. This update fixes the problem.

Original advisory details:

Jakub Wilk discovered that dpkg incorrectly certain paths and symlinks 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.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 14.04

• libdpkg-perl - 1.17.5ubuntu5.2

Ubuntu 13.10

• libdpkg-perl - 1.16.12ubuntu1.2

Ubuntu 12.10

Ubuntu 12.04

• libdpkg-perl - 1.16.1.2ubuntu7.4

Ubuntu 10.04

• dpkg-dev - 1.15.5.6ubuntu4.8

In general, a standard system update will make all the necessary changes.
