Description Josh Bressers 2005-11-07 12:48:36 EST
PHP exif data DoS

An error in the way php processes exif image data has been found.
This flaw will cause PHP to enter an infinite loop when
exif_read_data() against the malicious image.  The PHP process will
continue to consume computing resources until the PHP process is

When run through httpd, the PHP process will eventually timeout and be
killed.  This is only a temporary DoS when PHP is run from httpd..

This issue also affects RHEL3
This issue also affects RHEL2.1

This issue doesn't affect RHEL2.1 as exif_read_data is undefined and as per php
docs this function is available in PHP 4 >= 4.2.0, PHP 5 while RHEL-2.1 contains
