Red Hat Security Advisory
Synopsis: Updated php packages fix security issues
Advisory ID: RHSA-2005:031-01
Advisory URL: https://rhn.redhat.com/errata/RHSA-2005-031.html
Issue date: 2005-01-19

Product: Red Hat Enterprise Linux
CVE Names: CAN-2004-1018 CAN-2004-1019
- - ---------------------------------------------------------------------
1. Summary:
Updated php packages that fix various security issues are now
available for Red Hat Enterprise Linux 2.1.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64
Red Hat Linux Advanced Workstation 2.1 - ia64
Red Hat Enterprise Linux ES version 2.1 - i386
Red Hat Enterprise Linux WS version 2.1 - i386
3. Problem description:
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 allow a remote attacker to gain access to memory or potentially
execute arbitrary code. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-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 (cve.mitre.org) has assigned the name CAN-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.
4. Solution:
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied. Use Red Hat
Network to download and update your packages. To launch the Red Hat
Update Agent, use the following command:
