Upgrade Debian:8 enigmail to version 2:1.9.9-1~deb8u1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream enigmail package and not the enigmail package as distributed by Debian.
See How to fix? for Debian:8 relevant fixed versions and status.
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.
