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.
