Debian Logo
Mitigating privilege escalation in Dovecot on Debian involves adjusting permissions, configuring mail locations, isolating users, and applying ACLs for enhanced security
Prior to this update, the default configuration for Dovecot used by Debian runs the server daemons with group mail privileges

Summary


If your current configuration uses mail_extra_groups with a value
different from "mail", you may have to resort to the
mail_access_groups configuration directive.

For the stable distribution (etch), these problems have been fixed in
version 1.0.rc15-2etch4.

For the unstable distribution (sid), these problems have been fixed in
version 1.0.13-1.

For the old stable distribution (sarge), no updates are provided.
We recommend that you consider upgrading to the stable distribution.
