Scientific Linux Security Update : php on SL5.x i386/x86_64

This script is Copyright (C) 2013 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

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)

After installing the updated packages, the httpd daemon must be
restarted for the update to take effect.
