Debian DSA-4991-1 : mailman - security update

high Nessus Plugin ID 154354


The remote Debian host is missing one or more security-related updates.


The remote Debian 10 host has a package installed that is affected by multiple vulnerabilities as referenced in the dsa-4991 advisory.

- /options/mailman in GNU Mailman before 2.1.31 allows Arbitrary Content Injection. (CVE-2020-12108)

- GNU Mailman before 2.1.33 allows arbitrary content injection via the Cgi/ private archive login page. (CVE-2020-15011)

- GNU Mailman before 2.1.35 may allow remote Privilege Escalation. A certain csrf_token value is derived from the admin password, and may be useful in conducting a brute-force attack against that password.

- GNU Mailman before 2.1.35 may allow remote Privilege Escalation. A csrf_token value is not specific to a single user account. An attacker can obtain a value within the context of an unprivileged user account, and then use that value in a CSRF attack against an admin (e.g., for account takeover). (CVE-2021-42097)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.


Upgrade the mailman packages.
