"The remote Debian 10 host has packages installed that are affected by a vulnerability as referenced in the dla-3514
advisory.

  - Bouncy Castle For Java before 1.74 is affected by an LDAP injection vulnerability. The vulnerability only
    affects applications that use an LDAP CertStore from Bouncy Castle to validate X.509 certificates. During
    the certificate validation process, Bouncy Castle inserts the certificate's Subject Name into an LDAP
    search filter without any escaping, which leads to an LDAP injection vulnerability. (CVE-2023-33201)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
