-----BEGIN PGP SIGNED MESSAGE----- =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2003.0462 -- RHSA-2003:204-01 Updated PHP packages are now available 03 July 2003 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: PHP Publisher: Red Hat Operating System: Red Hat Linux 9 Red Hat Linux 8.0 Linux Impact: Execute Arbitrary Code/Commands Reduced Security Access Required: Remote CVE Names: CAN-2003-0442 - --------------------------BEGIN INCLUDED TEXT-------------------- - -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - - --------------------------------------------------------------------- Red Hat Security Advisory Synopsis: Updated PHP packages are now available Advisory ID: RHSA-2003:204-01 Issue date: 2003-07-02 Updated on: 2003-07-02 Product: Red Hat Linux Keywords: PHP Cross-Site-Scripting use_trans_sid session Cross references: Obsoletes: RHSA-2003:017 CVE Names: CAN-2003-0442 - - --------------------------------------------------------------------- 1. Topic: Updated PHP packages for Red Hat Linux 8.0 and 9 are available that fix a number of bugs, as well as a minor security problem in the transparent session ID functionality. 2. Relevant releases/architectures: Red Hat Linux 8.0 - i386 Red Hat Linux 9 - i386 3. Problem description: PHP is an HTML-embedded scripting language commonly used with the Apache HTTP server. This update contains fixes for a number of bugs discovered in the version of PHP included in Red Hat Linux 8.0 and 9. These bugs include the use of a PHP script as an ErrorDocument and possible POST body corruption in some configurations. Also included is a fix for a minor security problem. In PHP version 4.3.1 and earlier, when transparent session ID support is enabled using the "session.use_trans_sid" option, the session ID is not escaped before use. This allows a Cross Site Scripting attack. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0442 to this issue. All users of PHP are advised to upgrade to these erratum packages, which contain back-ported patches to correct these issues. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. To update all RPMs for your particular architecture, run: rpm -Fvh [filenames] where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory *only* contains the desired RPMs. Please note that this update is also available via Red Hat Network. Many people find this an easier way to apply updates. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. 5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info): 74761 - snmp module relocation error 82967 - POST body corruption in some configurations 84460 - pear/DB/pgsql.php incompatible with postgresql 7.3 84828 - exit() does not report correct exit code 85820 - ext/sockets.c has a bug in socket_write 91019 - ErrorDocument 401 /some_file.php does not work with apache2 91279 - Segfault using PHP with mod_negotiation 6.
