Coppermine Photo Gallery have a vulnerability, which can be
exploited by malicious users to compromise a vulnerable system.
The vulnerability is caused due to an error in the handling of
file uploads where a filename has multiple file extensions. This
can be exploited to upload malicious script files inside the web
root (e.g. a PHP script).
Successful exploitation may allow execution of script code
depending on the HTTP server configuration (it requires e.g. an
Apache server with the "mod_mime" module installed).
