Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS : mod_perl vulnerability (USN-3825-1)

critical Nessus Plugin ID 119118

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-3825-1 advisory.

 Jan Ingvoldstad discovered that mod_perl incorrectly handled configuration options to disable being used by unprivileged users, contrary to the documentation. A local attacker could possibly use this issue to execute arbitrary Perl code.

Tenable has extracted the preceding description block directly from the Ubuntu 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 libapache2-mod-perl2 and / or libapache2-mod-perl2-dev packages.
