Description

The vulnerability allows a remote attacker to conduct spoofing attack.

The vulnerability exists due to improper validation of OpenPGP signatures. A remote attacker can trick the victim into opening a malicious email with valid PGP-signed data as an attachment and either inject arbitrary script code, which could be used to trick the user into disclosing sensitive information, or conduct further attacks.
