RHEL 3 / 4 : php (RHSA-2005:831)
High Nessus Plugin ID 20206
SynopsisThe remote Red Hat host is missing one or more security updates.
DescriptionUpdated PHP packages that fix multiple security issues are now available for Red Hat Enterprise Linux 3 and 4.
This update has been rated as having moderate security impact by the Red Hat Security Response Team.
PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Web server.
A flaw was found in the way PHP registers global variables during a file upload request. A remote attacker could submit a carefully crafted multipart/form-data POST request that would overwrite the $GLOBALS array, altering expected script behavior, and possibly leading to the execution of arbitrary PHP commands. Please note that this vulnerability only affects installations which have register_globals enabled in the PHP configuration file, which is not a default or recommended option. The Common Vulnerabilities and Exposures project assigned the name CVE-2005-3390 to this issue.
A flaw was found in the PHP parse_str() function. If a PHP script passes only one argument to the parse_str() function, and the script can be forced to abort execution during operation (for example due to the memory_limit setting), the register_globals may be enabled even if it is disabled in the PHP configuration file. This vulnerability only affects installations that have PHP scripts using the parse_str function in this way. (CVE-2005-3389)
A denial of service flaw was found in the way PHP processes EXIF image data. It is possible for an attacker to cause PHP to crash by supplying carefully crafted EXIF image data. (CVE-2005-3353)
Users of PHP should upgrade to these updated packages, which contain backported patches that resolve these issues.
SolutionUpdate the affected packages.
