Ubuntu 5.10 / 6.06 LTS / 6.10 : tar vulnerability (USN-385-1)

Ubuntu Security Notice (C) 2006-2016 Canonical, Inc. / NASL script (C) 2007-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

Teemu Salmela discovered that tar still handled the deprecated
GNUTYPE_NAMES record type. This record type could be used to create
symlinks that would be followed while unpacking a tar archive. If a
user or an automated system were tricked into unpacking a specially
crafted tar file, arbitrary files could be overwritten with user
privileges.

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 tar package.

Risk factor :

Medium / CVSS Base Score : 4.0
(CVSS2#AV:N/AC:H/Au:N/C:N/I:P/A:P)
