Ubuntu Security Notice USN-2083-1

graphviz vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 13.10
- Ubuntu 13.04
- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 10.04 LTS

Summary:

Graphviz could be made to crash or run programs as your login if it opened
a specially crafted file.

Software Description:
- graphviz: rich set of graph drawing tools

Details:

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.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 13.10:
graphviz 2.26.3-15ubuntu4.1

Ubuntu 13.04:
graphviz 2.26.3-14ubuntu1.1

Ubuntu 12.10:
graphviz 2.26.3-12ubuntu1.1

Ubuntu 12.04 LTS:
graphviz 2.26.3-10ubuntu1.1

Ubuntu 10.04 LTS:
graphviz 2.20.2-8ubuntu3.1

In general, a standard system update will make all the necessary changes.
