|
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 type="normal">
|
|
<p>
|
|
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.
|
|
</p>
|

</impact>
|

<workaround>
|
|
<p>
|

There is no known workaround at this time.

All Graphviz users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=media-gfx/graphviz-2.20.3"</code>
