Description Huzaifa S. Sidhpurwala 2012-08-29 23:38:55 EDT
A heap-buffer overflow flaw was found in libxslt, a C library which allows to transform XML files into other XML files (or HTML, text, ...) using the standard XSLT stylesheet transformation mechanism. It was found that when applying templates to nodes selected by "namespace::*", a out-of-bounds read is performed. Later, this value is used during unlinking of nodes, leading to a WRITE error in xmlUnlinkNode().
