Description Huzaifa S. Sidhpurwala 2012-08-29 23:54:02 EDT
Two Use-after-frees were 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. One of them is caused due to an invalid XPath reference and the other is due to improper application of generate-id().
