Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that there was a directory traversal vulnerability in unrar-free, a unarchiver for .rar files, where pathnames of the form '../filename' were unpacked into the parent directory.

For Debian 7 'Wheezy', this issue has been fixed in unrar-free version 1:0.0.1+cvs20071127-2+deb7u1.

We recommend that you upgrade your unrar-free packages.

Solution

Upgrade the affected unrar-free package.
