http://security.gentoo.org/

Severity:	high
Title:	uw-imap: Remote buffer overflow
Date:	10/11/2005
Bugs:	#108206
ID:	200510-10

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	Architecture(s)
net-mail/uw-imap	< 2004g	>= 2004g	All supported architectures

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"
