Ubuntu 14.04 LTS / 16.04 LTS / 17.04 : graphite2 vulnerabilities (USN-3398-1)

Ubuntu Security Notice (C) 2017 Canonical, Inc. / NASL script (C) 2017 Tenable Network Security, Inc.


Synopsis :

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

Description :

Holger Fuhrmannek and Tyson Smith 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 : 6.9
(CVSS2#E:U/RL:OF/RC:C)
Public Exploit Available : false
