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

A memory corruption flaw was found in the way the openssl_x509_parse()
function of the PHP openssl extension parsed X.509 certificates. A remote
attacker could use this flaw to provide a malicious self-signed certificate
or a certificate signed by a trusted authority to a PHP application using
the aforementioned function, causing the application to crash or, possibly,
allow the attacker to execute arbitrary code with the privileges of the
user running the PHP interpreter. (CVE-2013-6420)

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 the PHP SOAP parser allowed the expansion of external XML
entities during SOAP message parsing. A remote attacker could possibly use
this flaw to read arbitrary files that are accessible to a PHP application
using a SOAP extension. (CVE-2013-1643)

Red Hat would like to thank the PHP project for reporting CVE-2013-6420.
Upstream acknowledges Stefan Esser as the original reporter.

All php users are advised to upgrade to these updated packages, which
contain backported patches to correct these issues. After installing the
updated packages, the httpd daemon must be restarted for the update to
take effect.
