Scientific Linux Security Update : php53 on SL5.x i386/x86_64

This script is Copyright (C) 2012 Tenable Network Security, Inc.


Synopsis :

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

Description :

A flaw was found in the way PHP converted certain floating point
values from string representation to a number. If a PHP script
evaluated an attacker's input in a numeric context, the PHP
interpreter could cause high CPU usage until the script execution time
limit is reached. This issue only affected i386 systems.
(CVE-2010-4645)

A stack memory exhaustion flaw was found in the way the PHP
filter_var() function validated email addresses. An attacker could use
this flaw to crash the PHP interpreter by providing excessively long
input to be validated as an email address. (CVE-2010-3710)

A memory disclosure flaw was found in the PHP multi-byte string
extension. If the mb_strcut() function was called with a length
argument exceeding the input string size, the function could disclose
a portion of the PHP interpreter's memory. (CVE-2010-4156)

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