Secunia

A security issue has been reported in multiple Horde products, which can be exploited by malicious users to bypass certain security restrictions.

The security issue is caused due to an error within the enforcing of access restriction policies imposed on the address book. This can be exploited to gain access to restricted contacts placed in the same SQL table, if the unique key of another user's contact can be obtained.

The security issue is reported in Horde Groupware 1.0.3, Horde Groupware Webmail Edition 1.0.4, and Turba Contact Manager 2.1.6. Prior versions may also be affected.

Solution
Update to Horde Groupware 1.0.4, Horde Groupware Webmail Edition 1.0.5, and Turba Contact Manager 2.1.7.
