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.

Graph drawing addresses the problem of visualizing structural information by constructing geometric representations of abstract graphs and networks. Automatic generation of graph drawings has important applications in key technologies such as database design, software engineering, VLSI and network design and visual interfaces in other domains. Situations where these tools might be particularly useful include:

graphviz on Debian Linux

This check tests the installed software version using the apt package manager.
