Background
tardiff is a package in the Debian 7 Wheezy ecosystem that provides a utility for comparing two tar archives and generating a diff file. It is commonly used for creating and applying patches to tar archives. The package is vulnerable to two security issues: CVE-2015-0857 and CVE-2015-0858.
Vulnerability Detail
CVE-2015-0857 allows for arbitrary command execution through shell metacharacters in the name of a tar file or a file within a tar file. This means that an attacker could manipulate the file names in a way that leads to the execution of arbitrary commands on the system. CVE-2015-0858 enables local users to write to arbitrary files by exploiting a symlink attack on a pathname in a temporary directory used by tardiff.
