PHP is an HTML-embedded scripting language commonly used with the
Apache HTTP Server.
It was found that the hashing routine used by PHP arrays was
susceptible to predictable hash collisions. If an HTTP POST request to
a PHP application contained many parameters whose names map to the
same hash value, a large amount of CPU time would be consumed. This
flaw has been mitigated by adding a new configuration directive,
max_input_vars, that limits the maximum number of parameters processed
per request. By default, max_input_vars is set to 1000.
An integer overflow flaw was found in the PHP exif extension. On
32-bit systems, a specially crafted image file could cause the PHP
interpreter to crash or disclose portions of its memory when a PHP
script tries to extract Exchangeable image file format (Exif) metadata
from the image file. (CVE-2011-4566)
All php53 and php users should upgrade to these updated packages,
which contain backported patches to resolve these issues. After
installing the updated packages, the httpd daemon must be restarted
for the update to take effect.
