Description:
A vulnerability has been reported in GnuPG, which can be exploited by malicious people to bypass certain security restrictions.
The vulnerability is caused due to an error in the detection of unsigned data. This makes it possible to inject arbitrary data into a signed message and affects the verification of non-detached signatures and signatures embedded in encrypted messages.
The vulnerability affects all versions prior to 1.4.2.2. Version 1.9.x (development branch) is not affected unless the deprecated gpg part has been enabled.
Solution:
Update to version 1.4.2.2 or later.
