GLSA-200611-10 : WordPress: Multiple vulnerabilities

This script is Copyright (C) 2006-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200611-10
(WordPress: Multiple vulnerabilities)

'random' discovered that users can enter serialized objects as strings
in their profiles that will be harmful when unserialized. 'adapter'
found out that user-edit.php fails to effectively deny non-permitted
users access to other user's metadata. Additionally, a directory
traversal vulnerability in the wp-db-backup module was discovered.

Impact :

By entering specially crafted strings in his profile, an attacker can
crash PHP or even the web server running WordPress. Additionally, by
crafting a simple URL, an attacker can read metadata of any other user,
regardless of their own permissions. A user with the permission to use
the database backup plugin can possibly overwrite files he otherwise
has no access to.

Workaround :

There is no known workaround at this time.
