Description Huzaifa S. Sidhpurwala 2011-03-12 01:14:23 EST
Chris Evans discovered a heap address leak in XSLT
The bug is in the generate-id() XPath function, and is 
sometimes used in XSL transforms. 
This is a low severity information leak, that does not
corrupt anything, However it can be paired with other 
bugs and can be perhaps used as an exploit aid against
ASLR.
