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

medium Nessus Plugin ID 60948

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.

Solution

Update the affected packages.
