DLA-3284-1 libapache-session-ldap-perl -- LTS security update

Date Reported:

28 Jan 2023

Affected Packages:

libapache-session-ldap-perl

Vulnerable:

Yes

Security database references:

In Mitre's CVE dictionary: CVE-2020-36658.

More information:

In Apache::Session::LDAP before 0.5, 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.

This update changes the default behavior to require X.509 validation against the distribution bundle /etc/ssl/certs/ca-certificates.crt. Previous behavior can reverted by setting ldapVerify => "none" when initializing the Apache::Session::LDAP object.

Note: this update is a prerequisite for LemonLDAP::NG's CVE-2020-16093 fix when its session backend is set to Apache::Session::LDAP.

For Debian 10 buster, this problem has been fixed in version 0.4-1+deb10u1.

We recommend that you upgrade your libapache-session-ldap-perl packages.
