[GLSA-200402-04] Gallery 1.4.1 and below remote exploit vulnerability

Vulnerability Assessment Summary
Gallery 1.4.1 and below remote exploit vulnerability

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200402-04
(Gallery 1.4.1 and below remote exploit vulnerability)

Starting in the 1.3.1 release, Gallery includes code to simulate the behaviour
of the PHP 'register_globals' variable in environments where that setting
is disabled. It is simulated by extracting the values of the various
$HTTP_ global variables into the global namespace.

Impact

A crafted URL such as
http://example.com/gallery/init.php?HTTP_POST_VARS=xxx causes the
'register_globals' simulation code to overwrite the $HTTP_POST_VARS which,
when it is extracted, will deliver the given payload. If the
payload compromises $GALLERY_BASEDIR then the malicious user can perform a
PHP injection exploit and gain remote access to the webserver with PHP
user UID access rights.

Workaround

The workaround for the vulnerability is to replace init.php and
setup/init.php with the files in the following ZIP file:
http://prdownloads.sourceforge.net/gallery/patch_1.4.1-to-1.4.1-pl1.zip?download

Solution:
All users are encouraged to upgrade their gallery installation:
# emerge sync
# emerge -p ">=app-misc/gallery-1.4.1_p1"
# emerge ">=app-misc/gallery-1.4.1_p1"

Network Security Threat Level: Medium
