PACKAGE : libxml2
SUMMARY : Fixes for libxml2 buffer overflow vulnerabilities
DATE : 2004-11-18 09:20:00
ID : CLA-2004:890
RELEVANT
RELEASES : 9, 10
- -------------------------------------------------------------------------
DESCRIPTION
The XML C library[1] (libxml2) is used by many programs to load and
save extensible data structures or to manipulate several kinds of XML
files.
This update fixes a buffer overflow vulnerability[2,3] in the URI
parsing code found by "infamous41md" at the nanoftp and nanohttp
modules of libxml2. An attacker may 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
It is recommended that all libxml/libxml2 users upgrade their
packages.
