+++ This bug was initially created as a clone of Bug #469415 +++ Description of problem: Copied from a post to imap-uw.edu: There is a security bug in versions of the programs tmail and dmail distributed with the IMAP Toolkit versions 2007c or earlier (all versions prior to 2008-10-29). This includes the version distributed with Alpine 2.00. A fixed version of the programs is included in the IMAP Toolkit version 2007d.[cut] If you are using tmail or dmail you should replace them with the fixed versions immediately. The bug is exploitable by local users with shell access and may be remotely exploitable on some systems. A default sendmail installation with tmail as a delivery agent is not remotely exploitable because of length limits imposed by sendmail.[cut] http://mailman2.u.washington.edu/pipermail/imap-uw/2008-October/002267.html
uw-imap-2007d-1.fc9 has been pushed to the Fedora 9 stable repository. If problems still persist, please make note of it in this bug report.
