Debian Security Advisory DSA-2257-1 [email protected]
http://www.debian.org/security/ Nico Golde
June 11, 2011 http://www.debian.org/security/faq
Package : kolab-cyrus-imapd
Vulnerability : implementation error
Problem type : remote
Debian-specific: no
CVE ID : CVE-2011-1926
Debian Bug : 629350
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.
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.
For the testing distribution (wheezy), this problem has been fixed in
version 2.2.13p1-0.1.
For the unstable distribution (sid), this problem has been fixed in
version 2.2.13p1-0.1.
We recommend that you upgrade your kolab-cyrus-imapd packages.
