Description

This update for enigmail to version 1.9.9 fixes the following issues (boo#1073858) :

  • Enigmail could be coerced to use a malicious PGP public key with a corresponding secret key controlled by an attacker

  • Enigmail could have replayed encrypted content in partially encrypted e-mails, allowing a plaintext leak

  • Enigmail could be tricked into displaying incorrect signature verification results

  • Specially crafted content may cause denial of service
