Debian Security Advisory DSA-3098-1                   security@debian.org

Package        : graphviz
CVE ID         : CVE-2014-9157
Debian Bug     : 772648

Joshua Rogers discovered a format string vulnerability in the yyerror
function in lib/cgraph/scan.l in Graphviz, a rich set of graph drawing
tools. An attacker could use this flaw to cause graphviz to crash or
possibly execute arbitrary code.

For the stable distribution (wheezy), this problem has been fixed in
version 2.26.3-14+deb7u2.

For the upcoming stable distribution (jessie), this problem will be
fixed soon in version 2.38.0-7.

For the unstable distribution (sid), this problem has been fixed in
version 2.38.0-7.

We recommend that you upgrade your graphviz packages.
