Ubuntu Security Notice (C) 2008-2016 Canonical, Inc. / NASL script (C) 2009-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related
patches.

Description :

Jonathan Smith discovered that the Archive::Tar Perl module did not
correctly handle symlinks when extracting archives. If a user or
automated system were tricked into opening a specially crafted tar
file, a remote attacker could over-write arbitrary files.
(CVE-2007-4829)

Tavis Ormandy and Will Drewry discovered that Perl did not correctly
handle certain utf8 characters in regular expressions. If a user or
automated system were tricked into using a specially crafted
expression, a remote attacker could crash the application, leading to
a denial of service. Ubuntu 8.10 was not affected by this issue.
(CVE-2008-1927)

A race condition was discovered in the File::Path Perl module's rmtree
function. If a local attacker successfully raced another user's call
of rmtree, they could create arbitrary setuid binaries. Ubuntu 6.06
and 8.10 were not affected by this issue. (CVE-2008-5302)

A race condition was discovered in the File::Path Perl module's rmtree
function. If a local attacker successfully raced another user's call
of rmtree, they could delete arbitrary files. Ubuntu 6.06 was not
affected by this issue. (CVE-2008-5303).

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 packages.
