DSA-1892-1 dovecot -- buffer overflow

Debian Security Advisory

DSA-1892-1 dovecot -- buffer overflow

Date Reported:

23 Sep 2009

Affected Packages:

dovecot

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 546656.
In Mitre's CVE dictionary: CVE-2009-2632, CVE-2009-3235.

More information:

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.

Fixed in:

Debian GNU/Linux 4.0 (etch)
