Detail
Problem Description: Updated mailman packages that fix one security issue and several bugs are now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Server (v. 7) - ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - x86_64 3. Description: Mailman is a program used to help manage email discussion lists. It was found that mailman did not sanitize the list name before passing it to certain MTAs. A local attacker could use this flaw to execute arbitrary code as the user running mailman. (CVE-2015-2775) This update also fixes the following bugs: * Previously, it was impossible to configure Mailman in a way that Domain-based Message Authentication, Reporting & Conformance (DMARC) would recognize Sender alignment for Domain Key Identified Mail (DKIM) signatures. Consequently, Mailman list subscribers that belonged to a mail server with a "reject" policy for DMARC, such as yahoo.com or AOL.com, were unable to receive Mailman forwarded messages from senders residing in any domain that provided DKIM signatures. With this update, domains with a "reject" DMARC policy are recognized correctly, and Mailman list administrators are able to configure the way these messages are handled. As a result, after a proper configuration, subscribers now correctly receive Mailman forwarded messages in this scenario. (BZ#1229288) * Previously, the /etc/mailman file had incorrectly set permissions, which in some cases caused removing Mailman lists to fail with a "'NoneType' object has no attribute 'close'" message. With this update, the permissions value for /etc/mailman is correctly set to 2775 instead of 0755, and removing Mailman lists now works as expected. (BZ#1229307) * Prior to this update, the mailman utility incorrectly installed the tmpfiles configuration in the /etc/tmpfiles.d/ directory. As a consequence, changes made to mailman tmpfiles configuration were overwritten if the mailman packages were reinstalled or updated. The mailman utility now installs the tmpfiles configuration in the /usr/lib/tmpfiles.d/ directory, and changes made to them by the user are preserved on reinstall or update. (BZ#1229306) All mailman users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. For details on how to apply this update, refer to: https://access.redhat.com/articles/11258 5. Bugs fixed (https://bugzilla.redhat.com/): 1208059 - CVE-2015-2775 mailman: directory traversal in MTA transports that deliver programmatically 1229288 - Yahoo.com and AOL DMARC reject policies cripples Mailman-2.1.12 - update to newer release 1229307 - /etc/mailman has wrong permissions 0755 instead of 2775 |
