Description Huzaifa S. Sidhpurwala 2012-04-22 06:17:04 UTC
Using the Address Sanitizer tool, security researcher Atte Kettunen from OUSPG found a heap corruption in gfxImageSurface which allows for invalid frees and possible remote code execution. This happens due to float error, resulting from graphics values being passed through different number systems.
