Description
This security bulletin contains information about 1 vulnerability.

The vulnerability allows a remote attacker to gain access to potentially sensitive information.
This vulnerability exists due to the insufficient validation of PGP encrypted emails. A remote attacker in possession of PGP encrypted emails can wrap them as sub-parts within a crafted multipart email, trick a victim to reply to this (benign looking) email and gain unauthorized access to sensitive information on the system.
This attack variant bypasses protection mechanisms implemented after the "EFAIL" attacks.
