PACKAGE : libxml2
SUMMARY : Buffer overflow vulnerability
DATE : 2004-03-31 18:05:00
ID : CLA-2004:836

RELEASES : 8, 9

DESCRIPTION
The XML C library (libxml2) is used by many programs to load and save
extensible datastructures or to manipulate several kinds of XML
files.
This update fixes a buffer overflow vulnerability[1,2] in the URI
parsing code of the nanoftp and nanohttp modules of libxml2. An
attacker can exploit this vulnerability to execute arbitrary code
with the privileges of the user running an affected application.
Depending of the scenario where this application is used, this
vulnerability can be remotely exploitable.
SOLUTION
All users should update.
