DESCRIPTION

The UW IMAP suite offers the dmail and tmail programs to transmit
emails to user’s mailbox, or to a chosen directory. For example:
dmail user+directory
tmail user+directory

However, if the directory name is too long, a buffer overflow
occurs. To exploit this vulnerability, the dmail/tmail program has
to be installed suid or sgid.

An attacker can thus obtain privileges of the user (suid) or of
the group (sgid).
