GLSA-200803-25 : Dovecot: Multiple vulnerabilities

Medium Nessus Plugin ID 31612


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


The remote host is affected by the vulnerability described in GLSA-200803-25 (Dovecot: Multiple vulnerabilities)

Dovecot uses the group configured via the 'mail_extra_groups' setting, which should be used to create lockfiles in the /var/mail directory, when accessing arbitrary files (CVE-2008-1199). Dovecot does not escape TAB characters in passwords when saving them, which might allow for argument injection in blocking passdbs such as MySQL, PAM or shadow (CVE-2008-1218).
Impact :

Remote attackers can exploit the first vulnerability to disclose sensitive data, such as the mail of other users, or modify files or directories that are writable by group via a symlink attack. Please note that the 'mail_extra_groups' setting is set to the 'mail' group by default when the 'mbox' USE flag is enabled.
The second vulnerability can be abused to inject arguments for internal fields. No exploitation vectors are known for this vulnerability that affect previously stable versions of Dovecot in Gentoo.
Workaround :

There is no known workaround at this time.


All Dovecot users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-mail/dovecot-1.0.13-r1' This version removes the 'mail_extra_groups' option and introduces a 'mail_privileged_group' setting which is handled safely.
