HTTP: PHP Exif Invalid Tag Data Buffer Overflow Attempt

This signature detects attempts to exploit a known vulnerability in the Exif module of PHP. Successful exploitation would cause the PHP interpreter to crash, leading to a denial of service condition.

Extended Description

exif.c in the Exif extension in PHP before 5.3.6 on 64-bit platforms performs an incorrect cast, which allows remote attackers to cause a denial of service (application crash) via an image with a crafted Image File Directory (IFD) that triggers a buffer over-read.
