Debian DLA-1507-1 : libapache2-mod-perl2 security update

critical Nessus Plugin ID 117593

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Jan Ingvoldstad discovered that libapache2-mod-perl2 allows attackers to execute arbitrary Perl code by placing it in a user-owned .htaccess file, because (contrary to the documentation) there is no configuration option that permits Perl code for the administrator's control of HTTP request processing without also permitting unprivileged users to run Perl code in the context of the user account that runs Apache HTTP Server processes.

For Debian 8 'Jessie', this problem has been fixed in version 2.0.9~1624218-2+deb8u3.

We recommend that you upgrade your libapache2-mod-perl2 packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
