Synopsis

The remote Debian host is missing a security-related update.

Description

The remote Debian 10 host has packages installed that are affected by a vulnerability as referenced in the dsa-4943 advisory.

Several vulnerabilities were discovered in lemonldap-ng, a Web-SSO system. The flaws could result in information disclosure, authentication bypass, or could allow an attacker to increase its authentication level or impersonate another user, especially when lemonldap-ng is configured to increase authentication level for users authenticated via a second factor. For the stable distribution (buster), these problems have been fixed in version 2.0.2+ds-7+deb10u6. We recommend that you upgrade your lemonldap-ng packages.
