FreeBSD : Python -- poplib module, when passed a user-controlled command, can have additional commands injected using newlines (6d3488ae-2e0f-11f1-88c7-00a098b42aeb)

medium Nessus Plugin ID 304664

Synopsis

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

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 6d3488ae-2e0f-11f1-88c7-00a098b42aeb advisory.

Python Software Foundation Security Developer reports:
The poplib module, when passed a user-controlled command, can have additional commands injected using newlines. Mitigation rejects commands containing control characters.

Tenable has extracted the preceding description block directly from the FreeBSD security advisory.

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 packages.
