Synopsis
========
libxml2 contains multiple buffer overflows which could lead to the
execution of arbitrary code.
Background
==========
libxml2 is an XML parsing library written in C.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-libs/libxml2 < 2.6.15 >= 2.6.15
Description
===========
Multiple buffer overflows have been detected in the nanoftp and
nanohttp modules. These modules are responsible for parsing URLs with
ftp information, and resolving names via DNS.
Impact
======
An attacker could exploit an application that uses libxml2 by forcing
it to parse a specially-crafted XML file, potentially causing remote
execution of arbitrary code.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All libxml2 users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/libxml2-2.6.15"
