Red Hat Security Advisory 2012-1265-01 - libxslt is a library for transforming XML files into other textual formats using the standard XSLT stylesheet transformation mechanism. 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.
