RHEL 4 : php (RHSA-2005:564)

critical Nessus Plugin ID 18648

Synopsis

The remote Red Hat host is missing one or more security updates for php.

Description

The remote Redhat Enterprise Linux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2005:564 advisory.

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

A bug was discovered in the PEAR XML-RPC Server package included in PHP.
If a PHP script is used which implements an XML-RPC Server using the PEAR XML-RPC package, then it is possible for a remote attacker to construct an XML-RPC request which can cause PHP to execute arbitrary PHP commands as the 'apache' user. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-1921 to this issue.

When using the default SELinux targeted policy on Red Hat Enterprise Linux 4, the impact of this issue is reduced since the scripts executed by PHP are constrained within the httpd_sys_script_t security context.

A race condition in temporary file handling was discovered in the shtool script installed by PHP. If a third-party PHP module which uses shtool was compiled as root, a local user may be able to modify arbitrary files.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-1751 to this issue.

Users of PHP should upgrade to these updated packages, which contain backported fixes for these issues.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL php package based on the guidance in RHSA-2005:564.
