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 ">=media-gfx/graphviz-2.20.3"
