**Name of the Vulnerable Software and Affected Versions**
OpenPGP (affected versions not specified)
**Description**
The issue allows remote attackers to recover part of the plaintext via a chosen-ciphertext attack when the first 2 bytes of a message block are known, and an oracle or other mechanism is available to determine whether an integrity check failed. This occurs when handling a message that was encrypted using cipher feedback (CFB) mode.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
