HTTP: PHP Exif Extension Thumbnail Buffer Overflow

This signature detects attempts to exploit a known vulnerability in the PHP. A successful attack can lead to a buffer overflow and arbitrary remote code execution within the context of the application.

Extended Description

The exif_ifd_make_value function in exif.c in the EXIF extension in PHP before 5.4.34, 5.5.x before 5.5.18, and 5.6.x before 5.6.2 operates on floating-point arrays incorrectly, which allows remote attackers to cause a denial of service (heap memory corruption and application crash) or possibly execute arbitrary code via a crafted JPEG image with TIFF thumbnail data that is improperly handled by the exif_thumbnail function.
