Mozilla Foundation Security Advisory 2010-30 Title: Integer Overflow in XSLT Node Sorting Impact: Critical Announced: June 22, 2010 Reporter: Martin Barbella Products: Firefox, Thunderbird, SeaMonkey Fixed in: Firefox 3.6.4 Firefox 3.5.10 Thunderbird 3.0.5 SeaMonkey 2.0.5 Description Security researcher Martin Barbella reported via TippingPoint's Zero Day Initiative that an XSLT node sorting routine contained an integer overflow vulnerability. In cases where one of the nodes to be sorted contained a very large text value, the integer used to allocate a memory buffer to store its value would overflow, resulting in too small a buffer being created. An attacker could use this vulnerability to write data past the end of the buffer, causing the browser to crash and potentially running arbitrary code on a victim's computer.
