DLA-1507-1 libapache2-mod-perl2 -- LTS security update

Date Reported:

18 Sep 2018

Affected Packages:

libapache2-mod-perl2

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 644169.
In Mitre's CVE dictionary: CVE-2011-2767.

More information:

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.
