RHEL 3 / 4 : php (RHSA-2006:0568)
High Nessus Plugin ID 22044
Synopsis
The remote Red Hat host is missing one or more security updates.
Description
Updated PHP packages that fix multiple security issues are now available for Red Hat Enterprise Linux 3 and 4.
This update has been rated as having moderate security impact by the Red Hat Security Response Team.
PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Web server.
A directory traversal vulnerability was found in PHP. Local users could bypass open_basedir restrictions allowing remote attackers to create files in arbitrary directories via the tempnam() function.
(CVE-2006-1494)
The wordwrap() PHP function did not properly check for integer overflow in the handling of the 'break' parameter. An attacker who could control the string passed to the 'break' parameter could cause a heap overflow. (CVE-2006-1990)
A flaw was found in the zend_hash_del() PHP function. For PHP scripts that rely on the use of the unset() function, a remote attacker could force variable initialization to be bypassed. This would be a security issue particularly for installations that enable the 'register_globals' setting. 'register_globals' is disabled by default in Red Hat Enterprise Linux. (CVE-2006-3017)
Users of PHP should upgrade to these updated packages, which contain backported patches that resolve these issues.
Solution
Update the affected packages.
