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

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)

function. If a user were tricked into opening a specially crafted dot file,

an attacker could cause Graphviz to crash, or possibly execute arbitrary

vulnerability to a denial of service.
