Package : libapache-session-ldap-perl
Version : 0.4-1+deb10u1
CVE ID : CVE-2020-36658

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.
