Scientific Linux Security Update : libxml2 on SL5.x, SL6.x i386/x86_64

This script is Copyright (C) 2012-2014 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

The libxml2 library is a development toolbox providing the
implementation of various XML standards.

Multiple integer overflow flaws, leading to heap-based buffer
overflows, were found in the way libxml2 handled documents that enable
entity expansion. A remote attacker could provide a large, specially
crafted XML file that, when opened in an application linked against
libxml2, would cause the application to crash or, potentially, execute
arbitrary code with the privileges of the user running the
application. (CVE-2012-2807)

A one byte buffer overflow was found in the way libxml2 evaluated
certain parts of XML Pointer Language (XPointer) expressions. A remote
attacker could provide a specially crafted XML file that, when opened
in an application linked against libxml2, would cause the application
to crash or, potentially, execute arbitrary code with the privileges
of the user running the application. (CVE-2011-3102)

All users of libxml2 are advised to upgrade to these updated packages,
which contain backported patches to correct these issues. The desktop
must be restarted (log out, then log back in) for this update to take
effect.
