Ubuntu Security Notice USN-567-1           January 10, 2008
dovecot vulnerability
CVE-2007-6598
Kwetsbare Ubuntu versies:

Ubuntu 7.04
Ubuntu 7.10

Kwetsbare pakketten:

Ubuntu 7.04

Ubuntu 7.10

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

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.
