Red Hat Product Errata RHSA-2012:1265 0 normal SHIPPED_LIVE Important: libxslt security update 2012-09-13 21:00:20 UTC

Description Huzaifa S. Sidhpurwala 2012-08-30 03:54:02 UTC 
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().
