Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

Mitre reports :

The HTBoundary_put_block function in HTBound.c for W3C libwww
(w3c-libwww) allows remote servers to cause a denial of service
(segmentation fault) via a crafted multipart/byteranges MIME message
that triggers an out-of-bounds read.

The big2_toUtf8 function in lib/xmltok.c in libexpat in Expat 2.0.1,
as used in the XML-Twig module for Perl, allows context-dependent
attackers to cause a denial of service (application crash) via an XML
document with malformed UTF-8 sequences that trigger a buffer
over-read, related to the doProlog function in lib/xmlparse.c, a
different vulnerability than CVE-2009-2625 and CVE-2009-3720.

The updatePosition function in lib/xmltok_impl.c in libexpat in Expat
2.0.1, as used in Python, PyXML, w3c-libwww, and other software,
allows context-dependent attackers to cause a denial of service
(application crash) via an XML document with crafted UTF-8 sequences
that trigger a buffer over-read, a different vulnerability than
CVE-2009-2625.
