Description Huzaifa S. Sidhpurwala 2012-08-27 00:07:28 EDT
Security researcher Nicolas Grégoire used the Address Sanitizer tool to discover an out-of-bounds read in the format-number feature of XSLT, which can cause inaccurate formatting of numbers and information leakage. This is not directly exploitable.
