CRITICAL:
Less critical

IMPACT:
Exposure of system information, DoS

WHERE:
>From remote

SOFTWARE:
FsPHPGallery 1.x
http://secunia.com/product/4207/

DESCRIPTION:
Two vulnerabilities have been reported in FsPHPGallery, which can be
exploited by malicious people to cause a DoS (Denial of Service) and
disclose system information.

1) The vulnerability is caused due to an input validation error when
resizing images. This can be exploited to cause a DoS on the server
by supplying a large size attribute for an image.

2) Input passed to the "dir" parameter in "index.php" isn't properly
verified before it is being used to list directories inside the web
root. This can be exploited to disclose the contents of arbitrary
directories using directory traversal attacks.

SOLUTION:
Update to version 1.2:
http://gallery.devrandom.org.uk/releases/fsphpgallery-1.2.tar.gz

PROVIDED AND/OR DISCOVERED BY:
