Description

Updated PHP packages that fix various security issues are now available.

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 bug was found in the way PHP processes IFF and JPEG images. It is possible to cause PHP to consume CPU resources for a short period of time by supplying a carefully crafted IFF or JPEG image. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2005-0524 and CVE-2005-0525 to these issues.

A buffer overflow bug was also found in the way PHP processes EXIF image headers. It is possible for an attacker to construct an image file in such a way that it could execute arbitrary instructions when processed by PHP. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2005-1042 to this issue.

A denial of service bug was found in the way PHP processes EXIF image headers. It is possible for an attacker to cause PHP to enter an infinite loop for a short period of time by supplying a carefully crafted image file to PHP for processing. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2005-1043 to this issue.

Several bug fixes are also included in this update :

  • The security fixes in RHSA-2004-687 to the 'unserializer' code introduced some performance issues.

  • In the gd extension, the 'imagecopymerge' function did not correctly handle transparency. The original image was being obscured in the resultant image.

  • In the curl extension, safe mode was not enforced for 'file:///' URL lookups (CVE-2004-1392).

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