Subject: CVE request - uw-imap
Hi!
uw-imap upstream released new version 2007d on friday, announcing it as
security update fixing some issues in dmail and tmail utilities:

Further digging into this, the issue seem to be a buffer overflow
(strcpy) when handling command line arguments (overlong mailbox
specification when utility is called with user+folder argument). This
can have security implications in the setups where tmail is installed
setuid root (according to the resources I found, that's required in
certain configurations; dmail is not expected to run under different
user), or when one of the utilities is configured as deliver agent in
the MTA.
Some further info I managed to collect is in our BZ:
