CVE-2017-17844 not yet assigned priority: Debian including 1 source packages (enigmail), 1 status rows across 1 suites (bullseye): resolved 1.
An issue was discovered in Enigmail before 1.9.9. A remote attacker can obtain cleartext content by sending an encrypted data block (that the attacker cannot directly decrypt) to a victim, and relying on the victim to automatically decrypt that block and then send it back to the attacker as quoted text, aka the TBE-01-005 "replay" issue.
