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.
