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-200411-05 (libxml2: Remotely exploitable buffer overflow)

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.

Solution

All libxml2 users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-libs/libxml2-2.6.15'
