GPG Suite 2018.3

Security Update

This releases addresses EFAIL on macOS Sierra and includes a fix for SigSpoof.
SigSpoof is an exploit affecting GnuPG < 2.2.8 which allowed an attacker to fake any signature under special circumstances. GPG Suite never used the --verbose option of GnuPG by default, so unless 'verbose' was manually added to gpg.conf , our users should have been unaffected by this vulnerability. Mitigations included in 2018.3 make sure that even users with the 'verbose' option in their gpg.conf are no longer affected.

EFAIL mitigations in GPGMail (10.13 and 10.12 only at the moment)

  • Remote content is no longer loaded within encrpyted messages
  • If a message contains more than one encrypted part only the first part is decrypted
  • In case of mixed content (plain content and encrypted content), the plain content is isolated
  • Additional mitigations for S/MIME since unfortunately Apple has yet to completely fix EFAIL
