Synopsis

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

Description

The remote Debian 10 host has a package installed that is affected by multiple vulnerabilities as referenced in the dla-3284 advisory.

------------------------------------------------------------------------- Debian LTS Advisory DLA-3284-1 [email protected] https://www.debian.org/lts/security/ Guilhem Moulin January 28, 2023 https://wiki.debian.org/LTS
-------------------------------------------------------------------------

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.
