Debian DLA-3287-1 : lemonldap-ng - LTS security update

high Nessus Plugin ID 170758

Synopsis

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

Description

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3287 advisory.

- In LemonLDAP::NG (aka lemonldap-ng) through 2.0.8, validity of the X.509 certificate is not checked by default when connecting to remote LDAP backends, because the default configuration of the Net::LDAPS module for Perl is used. (CVE-2020-16093)

- In LemonLDAP::NG before 2.0.15. some sessions are not deleted when they are supposed to be deleted according to the timeoutActivity setting. This can occur when there are at least two servers, and a session is manually removed before the time at which it would have been removed automatically.
(CVE-2022-37186)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade the lemonldap-ng packages.

For Debian 10 buster, these problems have been fixed in version 2.0.2+ds-7+deb10u8.
