Ubuntu 10.04 LTS / 12.04 LTS / 12.10 / 13.04 / 13.10 : graphviz vulnerabilities (USN-2083-1)

Ubuntu Security Notice (C) 2014-2016 Canonical, Inc. / NASL script (C) 2014-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

It was discovered that Graphviz incorrectly handled memory in the
yyerror function. If a user were tricked into opening a specially
crafted dot file, an attacker could cause Graphviz to crash, or
possibly execute arbitrary code. (CVE-2014-0978, CVE-2014-1235)

It was discovered that Graphviz incorrectly handled memory in the
chkNum function. If a user were tricked into opening a specially
crafted dot file, an attacker could cause Graphviz to crash, or
possibly execute arbitrary code. (CVE-2014-1236)

The default compiler options for affected releases should reduce the
vulnerability to a denial of service.

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 graphviz package.
