Description Huzaifa S. Sidhpurwala 2012-08-27 03:44:16 UTC 
Security researcher Frédéric Hoguin reported two related issues with the decoding of bitmap (.BMP) format images embedded in icon (.ICO) format files. When processing a negative "height" header value for the bitmap image, a memory corruption can be induced, allowing an attacker to write random memory and cause a crash. This crash may be potentially exploitable.
