Medium Nessus Plugin ID 43038


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


CVE reports :

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.


Update the affected package.
