PHP is an HTML-embedded scripting language commonly used with the Apache
HTTP Server.

It was found that PHP did not check for carriage returns in HTTP headers,
allowing intended HTTP response splitting protections to be bypassed.
Depending on the web browser the victim is using, a remote attacker could
use this flaw to perform HTTP response splitting attacks. (CVE-2011-1398)

An integer signedness issue, leading to a heap-based buffer underflow, was
found in the PHP scandir() function. If a remote attacker could upload an
excessively large number of files to a directory the scandir() function
runs on, it could cause the PHP interpreter to crash or, possibly, execute
arbitrary code. (CVE-2012-2688)

It was found that PHP did not correctly handle the magic_quotes_gpc
configuration directive. This could result in magic_quotes_gpc input
escaping not being applied in all cases, possibly making it easier for a
remote attacker to perform SQL injection attacks. (CVE-2012-0831)

These updated php packages also include numerous bug fixes and
enhancements. Space precludes documenting all of these changes in this
advisory. Users are directed to the Red Hat Enterprise Linux 6.4 Technical
Notes, linked to in the References, for information on the most significant
of these changes.

All users of php are advised to upgrade to these updated packages, which
fix these issues and add these enhancements. After installing the updated
packages, the httpd daemon must be restarted for the update to take effect.
