Ubuntu Security Notice (C) 2010-2016 Canonical, Inc. / NASL script (C) 2010-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

It was discovered that gzip incorrectly handled certain malformed
compressed files. If a user or automated system were tricked into
opening a specially crafted gzip file, an attacker could cause gzip to
crash or possibly execute arbitrary code with the privileges of the
user invoking the program. (CVE-2009-2624)

Aki Helin discovered that gzip incorrectly handled certain malformed
files compressed with the Lempel-Ziv-Welch (LZW) algorithm. If a
user or automated system were tricked into opening a specially crafted
gzip file, an attacker could cause gzip to crash or possibly execute
arbitrary code with the privileges of the user invoking the program.
(CVE-2010-0001).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution :

Update the affected gzip package.
