GLSA-200403-01 : Libxml2 URI Parsing Buffer Overflow Vulnerabilities

high Nessus Plugin ID 14452

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200403-01 (Libxml2 URI Parsing Buffer Overflow Vulnerabilities)

 Yuuichi Teranishi discovered a flaw in libxml2 versions prior to 2.6.6.
 When the libxml2 library fetches a remote resource via FTP or HTTP, libxml2 uses parsing routines that can overflow a buffer caused by improper bounds checking if they are passed a URL longer than 4096 bytes.
 Impact :

 If an attacker is able to exploit an application using libxml2 that parses remote resources, then this flaw could be used to execute arbitrary code.
 Workaround :

 No workaround is available; users are urged to upgrade libxml2 to 2.6.6.

Solution

All users are recommended to upgrade their libxml2 installation:
 # emerge sync # emerge -pv '>=dev-libs/libxml2-2.6.6' # emerge '>=dev-libs/libxml2-2.6.6'
