The author of Dovecot recently discovered a number of holes in the libsieve implementation of the Sieve protocol:
The versions of Sieve distributed with the 1.1.x releases of Dovecot on Gentoo are vulnerable. This includes the only stable version.
Suggested fix: address bug #285211.
Alternately, it might be safe to just bump the version of Sieve from within the ebuilds.
Yes, our "sieve" wasn't patched.

I think it's safe to close this now?
No, it is not. The gentoo security team will close this bug after the GLSA was sent.
