Ubuntu 14.04 LTS / 15.10 : graphite2 vulnerabilities (USN-2902-1)

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


Synopsis :

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

Description :

Yves Younan discovered that graphite2 incorrectly handled certain
malformed fonts. If a user or automated system were tricked into
opening a specially- crafted font file, a remote attacker could use
this issue to cause graphite2 to crash, resulting in a denial of
service, or possibly execute arbitrary code.

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 libgraphite2-3 package.

Risk factor :

High / CVSS Base Score : 9.3
(CVSS2#AV:N/AC:M/Au:N/C:C/I:C/A:C)
CVSS Temporal Score : 7.1
(CVSS2#E:U/RL:U/RC:UC)
