[GLSA-200504-15] PHP: Multiple vulnerabilities |
||
PHP: Multiple vulnerabilities Detailed Explanation for this Vulnerability Assessment The remote host is affected by the vulnerability described in GLSA-200504-15 (PHP: Multiple vulnerabilities) An integer overflow and an unbound recursion were discovered in the processing of Image File Directory tags in PHP's EXIF module (CVE-2005-1042, CVE-2005-1043). Furthermore, two infinite loops have been discovered in the getimagesize() function when processing IFF or JPEG images (CVE-2005-0524, CVE-2005-0525). Impact A remote attacker could craft an image file with a malicious EXIF IFD tag, a large IFD nesting level or invalid size parameters and send it to a web application that would process this user-provided image using one of the affected functions. This could result in denying service on the attacked server and potentially executing arbitrary code with the rights of the web server. Workaround There is no known workaround at this time.
