Ubuntu 6.06 LTS / 6.10 / 7.04 / 7.10 : dovecot vulnerabilities (USN-593-1)

Ubuntu Security Notice (C) 2008-2013 Canonical, Inc. / NASL script (C) 2008-2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

It was discovered that the default configuration of dovecot could
allow access to any email files with group 'mail' without verifying
that a user had valid rights. An attacker able to create symlinks in
their mail directory could exploit this to read or delete another
user's email. (CVE-2008-1199)

By default, dovecot passed special characters to the underlying
authentication systems. While Ubuntu releases of dovecot are not known
to be vulnerable, the authentication routine was proactively improved
to avoid potential future problems. (CVE-2008-1218).

Solution :

Update the affected dovecot-common, dovecot-imapd and / or
dovecot-pop3d packages.

Risk factor :

Medium / CVSS Base Score : 6.8
(CVSS2#AV:N/AC:M/Au:N/C:P/I:P/A:P)
