Vulnerability Assessment Details

[GLSA-200504-15] PHP: Multiple vulnerabilities

Vulnerability Assessment Summary
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.
