Debian DSA-3048-1 : apt - security update

low Nessus Plugin ID 78092

Language:

Synopsis

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

Description

Guillem Jover discovered that the changelog retrieval functionality in apt-get used temporary files in an insecure way, allowing a local user to cause arbitrary files to be overwritten.

This vulnerability is neutralized by the fs.protected_symlinks setting in the Linux kernel, which is enabled by default in Debian 7 Wheezy and up.

Solution

Upgrade the apt packages.

For the stable distribution (wheezy), this problem has been fixed in version 0.9.7.9+deb7u6.
