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'

Risk factor :

Critical / CVSS Base Score : 10.0
