Gentoo Linux Security Advisory GLSA 200612-10 - Tar does not properly extract archive elements using the GNUTYPE_NAMES record name, allowing files to be created at arbitrary locations using symlinks. Once a symlink is extracted, files after the symlink in the archive will be extracted to the destination of the symlink. Versions less than 1.16-r2 are affected.

Date: December 11, 2006
Bugs: #155901
ID: 200612-10

Synopsis
========

Tar is vulnerable to directory traversal possibly allowing for the
overwriting of arbitrary files.

Background
==========

The Tar program provides the ability to create and manipulate tar
archives.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-arch/tar < 1.16-r2 >= 1.16-r2

Description
===========

Tar does not properly extract archive elements using the GNUTYPE_NAMES
record name, allowing files to be created at arbitrary locations using
symlinks. Once a symlink is extracted, files after the symlink in the
archive will be extracted to the destination of the symlink.

Impact
======

An attacker could entice a user to extract a specially crafted tar
archive, possibly allowing for the overwriting of arbitrary files on
the system extracting the archive.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Tar users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=app-arch/tar-1.16-r2"

References
