Debian DSA-2915-1 : dpkg - security update

medium Nessus Plugin ID 73743

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

Jakub Wilk discovered that dpkg did not correctly parse C-style filename quoting, allowing for paths to be traversed when unpacking a source package - leading to the creation of files outside the directory of the source being unpacked.

The update to the stable distribution (wheezy) incorporates non-security changes that were targeted for the point release 7.5.

Solution

Upgrade the dpkg packages.

For the oldstable distribution (squeeze), this problem has been fixed in version 1.15.9.

For the stable distribution (wheezy), this problem has been fixed in version 1.16.13.
