PHP is a general-purpose scripting language widely used to develop
|
|
web-based applications. It can run inside a web server using the
|
|
mod_php module or the CGI version of PHP, or can run stand-alone in a
|
|
CLI.

<p>
|
|
An integer overflow and an unbound recursion were discovered in
|
|
the processing of Image File Directory tags in PHP's EXIF module
|
|
(CAN-2005-1042, CAN-2005-1043). Furthermore, two infinite loops have
|
|
been discovered in the getimagesize() function when processing IFF or
|
|
JPEG images (CAN-2005-0524, CAN-2005-0525).

<impact type="high">
|
|
<p>
|
|
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.
