Subject: [USN-349-1] gzip vulnerabilities

=========================================================== 
Ubuntu Security Notice USN-349-1         September 19, 2006
gzip vulnerabilities
CVE-2006-4334, CVE-2006-4335, CVE-2006-4336, CVE-2006-4337,
CVE-2006-4338
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 5.04
Ubuntu 5.10
Ubuntu 6.06 LTS

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 5.04:
  gzip                                     1.3.5-9ubuntu3.5

Ubuntu 5.10:
  gzip                                     1.3.5-11ubuntu2.1

Ubuntu 6.06 LTS:
  gzip                                     1.3.5-12ubuntu0.1

In general, a standard system upgrade is sufficient to effect the
necessary changes.

Details follow:

Tavis Ormandy discovered that gzip did not sufficiently verify the
validity of gzip or compress archives while unpacking. By tricking an
user or automated system into unpacking a specially crafted compressed
file, this could be exploited to execute arbitrary code with the
user's privileges.
