Description Jan Lieskovsky 2012-05-16 10:56:13 UTC
An off-by-one out-of-bounds write flaw was found in the way libxml, a library for providing XML and HTML support, evaluated certain XPointer parts (XPointer is used by libxml to include only the part from the returned XML document, that can be accessed using the XPath expression given with the XPointer). A remote attacker could provide a specially-crafted XML file, which once opened in an application, linked against libxml, would lead to that application crash, or, potentially arbitrary code execution with the privileges of the user running the application.

Note: The flaw to be exploited requires the particular application, linked against libxml, to use the XPointer evaluation functionality.
