Debian DSA-2258-1 : kolab-cyrus-imapd - implementation error

medium Nessus Plugin ID 55065

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

It was discovered that the STARTTLS implementation of the Kolab Cyrus IMAP server does not properly restrict I/O buffering, which allows man-in-the-middle attackers to insert commands into encrypted IMAP, LMTP, NNTP and POP3 sessions by sending a cleartext command that is processed after TLS is in place.

Solution

Upgrade the kolab-cyrus-imapd packages.

For the oldstable distribution (lenny), this problem has been fixed in version 2.2.13-5+lenny3.

For the stable distribution (squeeze), this problem has been fixed in version 2.2.13-9.1.
