Synopsis
========
uw-imap is vulnerable to remote overflow of a buffer in the IMAP server
leading to execution of arbitrary code.
Background
==========
uw-imap is the University of Washington's IMAP and POP server daemons.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-mail/uw-imap < 2004g >= 2004g
Description
===========
Improper bounds checking of user supplied data while parsing IMAP
mailbox names can lead to overflowing the stack buffer.
Impact
======
Successful exploitation requires an authenticated IMAP user to request
a malformed mailbox name. This can lead to execution of arbitrary code
with the permissions of the IMAP server.
Workaround
==========
There are no known workarounds at this time.
Resolution
==========
All uw-imap users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-mail/uw-imap-2004g"
