Title: Graphviz: User-assisted execution of arbitrary code
Date: November 09, 2008
Bugs: #240636
ID: 200811-04
Synopsis
=======
A buffer overflow in Graphviz might lead to user-assisted execution of
arbitrary code via a DOT file.
Background
=========
Graphviz is an open source graph visualization software.
Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-gfx/graphviz < 2.20.3 >= 2.20.3
==========
Roee Hay reported a stack-based buffer overflow in the push_subg()
function in parser.y when processing a DOT file with a large number of
Agraph_t elements.
Impact
=====
A remote attacker could entice a user or automated system to open a
specially crafted DOT file in an application using Graphviz, possibly
leading to the execution of arbitrary code.
Workaround
=========
There is no known workaround at this time.
Resolution
=========
All Graphviz users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/graphviz-2.20.3"
