10 January 2008

Dovecot vulnerability

Releases

Packages

Details

It was discovered that in very rare configurations using LDAP, Dovecot may
reuse cached connections for users with the same password. As a result,
a user may be able to login as another if the connection is reused.
The default Ubuntu configuration of Dovecot was not vulnerable.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 7.10
Ubuntu 7.04

In general, a standard system upgrade is sufficient to effect the
necessary changes.
