DESCRIPTION:
Multiple vulnerabilities have been reported in PHP, where some have

cause a DoS (Denial of Service).

exploited to cause infinite loops and consume all available CPU
resources via a specially crafted image.

Other versions may also be affected.

2) Multiple unspecified security issues exist in the exif and fbsql
extensions and in the "unserialize()" and "swf_definepoly()" PHP
functions.

related.
