- ------------------------------------------------------------------------

Packages       : dovecot
Vulnerability  : buffer overflow
Problem type   : local (remote)
Debian-specific: no
CVE IDs        : CVE-2009-2632 CVE-2009-3235
Debian Bug     : 546656

It was discovered that the SIEVE component of dovecot, a mail server
that supports mbox and maildir mailboxes, is vulnerable to a buffer
overflow when processing SIEVE scripts. This can be used to elevate
privileges to the dovecot system user.  An attacker who is able to
install SIEVE scripts executed by the server is therefore able to read
and modify arbitrary email messages on the system.


For the oldstable distribution (etch), this problem has been fixed in version
1.0.rc15-2etch5.

For the stable distribution (lenny), this problem has been fixed in version
1:1.0.15-2.3+lenny1.

For the testing distribution (squeeze) and the unstable distribution
(sid), this problem has been fixed in version 1:1.2.1-1.


We recommend that you upgrade your dovecot packages.


Upgrade instructions
- --------------------

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
