Title:	RedHat Update for mailman RHSA-2015:1417-01
Summary:	The remote host is missing an update for the 'mailman'; package(s) announced via the referenced advisory.
Description:	Summary: The remote host is missing an update for the 'mailman' package(s) announced via the referenced advisory. Vulnerability Insight: Mailman is a program used to help manage e-mail 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) It was found that mailman stored private email messages in a world-readable directory. A local user could use this flaw to read private mailing list archives. (CVE-2002-0389) 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#1095359) * Mailman used a console encoding when generating a subject for a 'welcome email' when new mailing lists were created by the 'newlist' command. Consequently, when the console encoding did not match the encoding used by Mailman for that particular language, characters in the 'welcome email' could be displayed incorrectly. Mailman has been fixed to use the correct encoding, and characters in the 'welcome email' are now displayed properly. (BZ#1056366) * The 'rmlist' command used a hardcoded path to list data based on the VAR_PREFIX configuration variable. As a consequence, when the list was created outside of VAR_PREFIX, it was impossible to remove it using the 'rmlist' command. With this update, the 'rmlist' command uses the correct LIST_DATA_DIR value instead of VAR_PREFIX, and it is now possible to remove the list in described situation. (BZ#1008139) * Due to an incompatibility between Python and Mailman in Red Hat Enterprise Linux 6, when moderators were approving a moderated message to a mailing list and checked the 'Preserve messages for the site administrator' checkbox, Mailman failed to approve the message and returned an error. This incompatibility has been fixed, and Mailman now approves messages as expected in this scenario. (BZ#765807) * When Mailman was set to no ...
