Test ID:1.3.6.1.4.1.25623.1.0.892200
Category:Debian Local Security Checks
Title:Debian: Security Advisory (DLA-2200-1)
Summary:The remote host is missing an update for the Debian 'mailman' package(s) announced via the DLA-2200-1 advisory.
Description:Summary:
The remote host is missing an update for the Debian 'mailman' package(s) announced via the DLA-2200-1 advisory.

Vulnerability Insight:
A vulnerability was discovered in mailman. 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.

For Debian 8 Jessie, this problem has been fixed in version 1:2.1.18-2+deb8u5.

We recommend that you upgrade your mailman packages.

Affected Software/OS:
'mailman' package(s) on Debian 8.

Solution:
Please install the updated package(s).
