The remote Scientific Linux host is missing a security update.
A flaw was discovered in the way Dovecot handled the
'mail_extra_groups' option. An authenticated attacker with local shell
access could leverage this flaw to read, modify, or delete other users
mail that is stored on the mail server. (CVE-2008-1199)
This issue did not affect the default Red Hat Enterprise Linux 5
Dovecot configuration. This update adds two new configuration options
-- 'mail_privileged_group' and 'mail_access_groups' -- to minimize the
usage of additional privileges.
A directory traversal flaw was discovered in Dovecot's zlib plug-in.
An authenticated user could use this flaw to view other compressed
mailboxes with the permissions of the Dovecot process. (CVE-2007-2231)
A flaw was found in the Dovecot ACL plug-in. User with only insert
permissions for a mailbox could use the 'COPY' and 'APPEND' commands
to set additional message flags. (CVE-2007-4211)
A flaw was found in a way Dovecot cached LDAP query results in certain
configurations. This could possibly allow authenticated users to log
in as a different user who has the same password. (CVE-2007-6598)
As well, this updated package fixes the following bugs :
- configuring 'userdb' and 'passdb' to use LDAP caused
Dovecot to hang. A segmentation fault may have occurred.
In this updated package, using an LDAP backend for
'userdb' and 'passdb' no longer causes Dovecot to hang.
- the Dovecot 'login_process_size' limit was configured
for 32-bit systems. On 64-bit systems, when Dovecot was
configured to use either IMAP or POP3, the log in
processes crashed with out-of-memory errors. Errors such
as the following were logged :
pop3-login: pop3-login: error while loading shared libraries:
libsepol.so.1: failed to map segment from shared object: Cannot
In this updated package, the 'login_process_size' limit is correctly
configured on 64-bit systems, which resolves this issue.
Note: this updated package upgrades dovecot to version 1.0.7. For
further details, refer to the Dovecot changelog:
