Description:
Gerardo Richarte has reported a vulnerability in Evolution, which can be exploited by malicious people to bypass certain security restrictions.
The vulnerability is caused due to Evolution not calling GnuPG with the "--status-fd" option when verifying signatures. 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 is reported in 2.8.1. Other versions may also be affected.
Solution:
Verify signatures manually.
Provided and/or discovered by:
Gerardo Richarte, Core Security Technologies
