Synopsis

The remote Oracle Linux host is missing a security update.

Description

The remote Oracle Linux 8 host has a package installed that is affected by a vulnerability as referenced in the ELSA-2020-4667 advisory.

- GNU Mailman 2.x before 2.1.30 uses the .obj extension for scrubbed application/octet-stream MIME parts.
This behavior may contribute to XSS attacks against list-archive visitors, because an HTTP reply from an archive web server may lack a MIME type, and a web browser may perform MIME sniffing, conclude that the MIME type should have been text/html, and execute JavaScript code. (CVE-2020-12137)

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

Solution

Update the affected mailman package.
