There is a local privilege escalation in the maidag utility:
https://savannah.gnu.org/forum/forum.php?forum_id=9586
This version fixes important security flow. The maidag utility has
been withdrawn and three new programs have been included to provide
its functionality: local mail delivery agent mda, LMTP daemon lmtpd,
and user mail delivery tool putmail.
https://git.savannah.gnu.org/cgit/mailutils.git/plain/NEWS
* The maidag utility is withdrawn
The main purpose of this utility was to work as local mail delivery
agent (MDA), a program responsible for final delivery of email messages
to the recipient's mailbox. As such it required suid privileges.
In parallel with its main purpose, it also was able to work in two
other modes: the 'url' mode, designed to deliver mails to arbitrary
mailbox URLs, and 'lmtp' mode, in which it acted as local mail
transport daemon. Neither of these needed suid privileges.
The unfortunate design decision to combine the three modes in a single
versatile tool resulted in local privilege escalation threat in 'url'
mode.
To fix this, maidag has been replaced by three different utilities,
each one with a precisely defined purpose and carefully designed
privileges: mda, lmtpd, and putmail.

As this is listed as 'fixed in 3.8', it should be fixed in the 3.8 upload.
However, the upload didn't close this bug or mention the CVE. Closing the bug
now.
Thanks for the upload!
