An updated mangodb package has been released for Debian 7 LTS to address an upgrade issue with the last security update

Package : mongodb
Version : 2.0.6-1+deb7u1
CVE ID : CVE-2016-6494
Debian Bug : 832908, 833087

This is an update of DLA-558-1. The previous build had
revision number that was considered lower than the one
in wheezy and was therefore not installed at upgrade.

The text for DLA-558-1 is included here for reference
(with some improvement).

Two security related problems have been found in the mongodb
package, both related to logging.

CVE-2016-6494
World-readable .dbshell history file

Debian Bug 833087
Bruteforcable challenge responses in unprotected logfile

For Debian 7 "Wheezy", these problems have been fixed in version
2.0.6-1.1+deb7u1.

We recommend that you upgrade your mongodb packages.
