CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:H/Au:N/C:C/I:C/A:C

Detection Type:
Linux Distribution Package

Summary:
Check the version of mailman

Detection Method:
Checks if a vulnerable version is present on the target host.

Technical Details:
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 Linux Distribution 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 Linux Distribution Packages, which contain backported patches to correct these issues.

Affected Versions:
mailman on CentOS 7

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
