VERIFY ADVISORY: http://secunia.com/advisories/13074/
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: Reported by the vendor.
