CVE-2009-3720
First published: Sat Jan 17 2009(Updated: )
Peter Valchev discovered a flaw in the way expat handled malformed UTF-8 sequences when processing XML files. Incorrect UTF-8 sequenced could cause expat to fail to properly detect end of input and continue reading behind the end of input buffer. This results in a crash once reading reaches unmapped memory. Non-public upstream bug report: <a href="http://sourceforge.net/tracker/?func=detail&aid=1990430&group_id=10127&atid=110127">http://sourceforge.net/tracker/?func=detail&aid=1990430&group_id=10127&atid=110127</a> Contents of the report leaked via expat-bugs mailing list posts: <a href="http://mail.python.org/pipermail/expat-bugs/2009-January/002781.html">http://mail.python.org/pipermail/expat-bugs/2009-January/002781.html</a> Upstream patch: <a href="http://expat.cvs.sourceforge.net/viewvc/expat/expat/lib/xmltok_impl.c?r1=1.13&r2=1.15">http://expat.cvs.sourceforge.net/viewvc/expat/expat/lib/xmltok_impl.c?r1=1.13&r2=1.15</a> References: <a href="http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=551936">http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=551936</a> <a href="https://bugs.gentoo.org/show_bug.cgi?id=280615">https://bugs.gentoo.org/show_bug.cgi?id=280615</a>
