Synopsis:          Important: libxslt security update
Issue Date:        2012-09-13
CVE Numbers:       CVE-2011-1202
                    CVE-2011-3970
                    CVE-2012-2825
                    CVE-2012-2871
                    CVE-2012-2870

A heap-based buffer overflow flaw was found in the way libxslt applied
templates to nodes selected by certain namespaces. An attacker could use
this flaw to create a malicious XSL file that, when used by an application
linked against libxslt to perform an XSL transformation, could cause the
application to crash or, possibly, execute arbitrary code with the
privileges of the user running the application. (CVE-2012-2871)

Several denial of service flaws were found in libxslt. An attacker could
use these flaws to create a malicious XSL file that, when used by an
application linked against libxslt to perform an XSL transformation, could
cause the application to crash. (CVE-2012-2825, CVE-2012-2870,
CVE-2011-3970)

An information leak could occur if an application using libxslt processed
an untrusted XPath expression, or used a malicious XSL file to perform an
XSL transformation. If combined with other flaws, this leak could possibly
help an attacker bypass intended memory corruption protections.
(CVE-2011-1202)

All running applications linked against libxslt must be restarted for this
update to take effect.
