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 >=3D 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 ">=3Dmedia-gfx/graphviz-2.20.3"
