patch available.

  - Any project that parses untrusted Protocol Buffers data containing an arbitrary number of nested groups /
    series of SGROUP tags can corrupted by exceeding the stack limit i.e. StackOverflow. Parsing nested groups
    as unknown fields with DiscardUnknownFieldsParser or Java Protobuf Lite parser, or against Protobuf map
    fields, creates unbounded recursions that can be abused by an attacker. (CVE-2024-7254)

Note that Nessus relies on the presence of the package as reported by the vendor.");
