Synopsis

Gallery is possibly vulnerable to a cross-site scripting attack that could allow arbitrary JavaScript code execution.

2.  Impact Information

Background

Gallery is a web application written in PHP which is used to organize and publish photo albums. It allows multiple users to build and maintain their own albums. It also supports the mirroring of images on other servers.

Description

Peter Schumacher discovered that Gallery fails to sanitize the fullname set by users, possibly leading to a cross-site scripting vulnerability.

Impact

By setting a specially crafted fullname, an attacker can inject and execute script code in the victim's browser window and potentially compromise the user's gallery.

3.  Resolution Information

Workaround

There is no known workaround at this time.

Resolution

All Gallery users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=www-apps/gallery-1.5.2"

Note: Users with the vhosts USE flag set should manually use webapp-config to finalize the update.
