Severity: Normal
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

Description

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 &quot;&gt;=media-gfx/graphviz-2.20.3&quot;
