news 28 Posted April 14, 2009 -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: php security update Advisory ID: RHSA-2009:0350-01 Product: Red Hat Application Stack Advisory URL: https://rhn.redhat.com/errata/RHSA-2009-0350.html Issue date: 2009-04-14 CVE Names: CVE-2008-3658 CVE-2008-3660 CVE-2008-5498 CVE-2008-5557 CVE-2008-5658 CVE-2008-5814 CVE-2009-0754 CVE-2009-1271 ===================================================================== 1. Summary: Updated php packages that fix several security issues are now available for Red Hat Application Stack v2. This update has been rated as having moderate security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat Application Stack v2 for Enterprise Linux (v.5) - i386, x86_64 3. Description: PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Web server. A heap-based buffer overflow flaw was found in PHP's mbstring extension. A remote attacker able to pass arbitrary input to a PHP script using mbstring conversion functions could cause the PHP interpreter to crash or, possibly, execute arbitrary code. (CVE-2008-5557) A flaw was found in the handling of the "mbstring.func_overload" configuration setting. A value set for one virtual host, or in a user's .htaccess file, was incorrectly applied to other virtual hosts on the same server, causing the handling of multibyte character strings to not work correctly. (CVE-2009-0754) A directory traversal flaw was found in PHP's ZipArchive::extractTo function. If PHP is used to extract a malicious ZIP archive, it could allow an attacker to write arbitrary files anywhere the PHP process has write permissions. (CVE-2008-5658) A buffer overflow flaw was found in PHP's imageloadfont function. If a PHP script allowed a remote attacker to load a carefully crafted font file, it could cause the PHP interpreter to crash or, possibly, execute arbitrary code. (CVE-2008-3658) A flaw was found in the way PHP handled certain file extensions when running in FastCGI mode. If the PHP interpreter was being executed via FastCGI, a remote attacker could create a request which would cause the PHP interpreter to crash. (CVE-2008-3660) A memory disclosure flaw was found in the PHP gd extension's imagerotate function. A remote attacker able to pass arbitrary values as the "background color" argument of the function could, possibly, view portions of the PHP interpreter's memory. (CVE-2008-5498) A cross-site scripting flaw was found in a way PHP reported errors for invalid cookies. If the PHP interpreter had "display_errors" enabled, a remote attacker able to set a specially-crafted cookie on a victim's system could possibly inject arbitrary HTML into an error message generated by PHP. (CVE-2008-5814) A flaw was found in PHP's json_decode function. A remote attacker could use this flaw to create a specially-crafted string which could cause the PHP interpreter to crash while being decoded in a PHP script. (CVE-2009-1271) All php users are advised to upgrade to these updated packages, which contain backported patches to resolve these issues. The httpd web server must be restarted for the changes to take effect. 4.
