Security Fix(es): A flaw was found in the 389-ds-base LDAP Server. This issue occurs when issuing a Modify DN LDAP operation through the ldap protocol, when the function return value is not tested and a NULL pointer is dereferenced. If a privileged user performs a ldap MODDN operation after a failed operation, it could lead to a Denial of Service (DoS) or system crash. (CVE-2025-2487) A denial of service vulnerability was found in 389-ds-base ldap server. This issue may allow an authenticated user to cause a server crash while modifying `userPassword` using malformed input. (CVE-2024-2199) A denial of service vulnerability was found in the 389-ds-base LDAP server. This issue may allow an authenticated user to cause a server denial of service while attempting to log in with a user with a malformed hash in their password. (CVE-2024-5953) A flaw was found in the 389 Directory Server. This flaw allows an unauthenticated user to cause a systematic server crash while sending a specific extended search request, leading to a denial of service. (CVE-2024-6237) A flaw was found in 389-ds-base. A specially-crafted LDAP query can potentially cause a failure on the directory server, leading to a denial of service (CVE-2024-3657) rust-openssl is a set of OpenSSL bindings for the Rust programming language. In affected versions `ssl::select_next_proto` can return a slice pointing into the `server` argument_x27;s buffer but with a lifetime bound to the `client` argument. In situations where the `sever` buffer_x27;s lifetime is shorter than the `client` buffer_x27;s, this can cause a use after free. This could cause the server to crash or to return arbitrary memory contents to the client. The crate`openssl` version 0.10.70 fixes the signature of `ssl::select_next_proto` to properly constrain the output buffer_x27;s lifetime to that of both input buffers. Users are advised to upgrade. In standard usage of `ssl::select_next_proto` in the callback passed to `SslContextBuilder::set_alpn_select_callback`, code is only affected if the `server` buffer is constructed *within* the callback.
