Vulnerability Assessment Details

RHSA-2005-031: php

Vulnerability Assessment Summary
Check for the version of the php packages

Detailed Explanation for this Vulnerability Assessment

Updated php packages that fix various security issues are now
available for Red Hat Enterprise Linux 2.1.

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

A double-free bug was found in the deserialization code of PHP. PHP
applications use the unserialize function on untrusted user data, which
could permit a remote attacker to gain access to memory or potentially
execute arbitrary code. The Common Vulnerabilities and Exposures project
( has assigned the name CVE-2004-1019 to this issue.

Flaws were found in the pack and unpack PHP functions. These functions
do not normally pass user supplied data, so they would require a malicious
PHP script to be exploited. The Common Vulnerabilities and Exposures
project ( has assigned the name CVE-2004-1018 to this issue.

A bug was discovered in the initialization of the OpenSSL library, such
that the curl extension could not be used to perform HTTP requests over SSL
unless the php-imap package was installed.

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