The remote host is affected by the vulnerability described in GLSA-200812-16 (Dovecot: Multiple vulnerabilities)
Several vulnerabilities were found in Dovecot:
The 'k' right in the acl_plugin does not work as expected (CVE-2008-4577, CVE-2008-4578) The dovecot.conf is world-readable, providing improper protection for the ssl_key_password setting (CVE-2008-4870) A permanent Denial of Service with broken mail headers is possible (CVE-2008-4907) Impact :
These vulnerabilities might allow a remote attacker to cause a Denial of Service, to circumvent security restrictions or allow local attackers to disclose the passphrase of the SSL private key.
Workaround :
There is no known workaround at this time.
