Ubuntu 12.04 LTS / 14.04 LTS / 14.10 : libarchive vulnerabilities (USN-2549-1)

Ubuntu Security Notice (C) 2015-2016 Canonical, Inc. / NASL script (C) 2015-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

It was discovered that the libarchive bsdcpio utility extracted
absolute paths by default without using the --insecure flag, contrary
to expectations. If a user or automated system were tricked into
extracting cpio archives containing absolute paths, a remote attacker
may be able to write to arbitrary files. (CVE-2015-2304)

Fabian Yamaguchi discovered that libarchive incorrectly handled
certain type conversions. A remote attacker could possibly use this
issue to cause libarchive to crash, resulting in a denial of service.
This issue only affected Ubuntu 12.04 LTS. (CVE-2013-0211).

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 bsdcpio, libarchive12 and / or libarchive13
packages.

Risk factor :

Medium / CVSS Base Score : 6.4
(CVSS2#AV:N/AC:L/Au:N/C:N/I:P/A:P)
CVSS Temporal Score : 5.6
(CVSS2#E:ND/RL:OF/RC:C)
Public Exploit Available : false
