Descriptions

libraries/libldap/tls_m.c in OpenLDAP, possibly 2.4.31 and earlier, when using the Mozilla NSS backend, always uses the default cipher suite even when TLSCipherSuite is set, which might cause OpenLDAP to use weaker ciphers than intended and make it easier for remote attackers to obtain sensitive information.

libraries/libldap/tls_m.c en OpenLDAP, posiblemente v2.4.31 y anteriores, cuando se utiliza el "backend" de Mozilla NSS, siempre utiliza la suite de cifrado por defecto incluso cuando TLSCipherSuite está establecido, lo que podría provocar que OpenLDAP use algoritmos de cifrado más débiles que los esperados y que sea más fácil para que los atacantes remotos obtener información sensible.

OpenLDAP is an open source suite of LDAP applications and development tools. It was found that the OpenLDAP server daemon ignored olcTLSCipherSuite settings. This resulted in the default cipher suite always being used, which could lead to weaker than expected ciphers being accepted during Transport Layer Security negotiation with OpenLDAP clients.
