Debian Linux Security Advisory 2242-1 - It was discovered that the STARTTLS implementation of the 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.

Debian-specific: no
CVE ID : CVE-2011-1926
Debian Bug : 627081

It was discovered that the STARTTLS implementation of the 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.

For the oldstable distribution (lenny), this problem has been fixed in
version 2.2.13-14+lenny4.

For the stable distribution (squeeze), this problem has been fixed in
version 2.2.13-19+squeeze1.

For the unstable distribution (sid), this problem has been fixed in
version 2.2.13p1-11 for cyrus-imapd-2.2 and in version 2.4.7-1
for cyrus-imapd-2.4.

We recommend that you upgrade your cyrus-imapd-2.2 packages.
