"The remote Rocky Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the
RLSA-2024:2549 advisory.

  - The protojson.Unmarshal function can enter an infinite loop when unmarshaling certain forms of invalid
    JSON. This condition can occur when unmarshaling into a message which contains a google.protobuf.Any
    value, or when the UnmarshalOptions.DiscardUnknown option is set. (CVE-2024-24786)

  - Package jose aims to provide an implementation of the Javascript Object Signing and Encryption set of
    standards. An attacker could send a JWE containing compressed data that used large amounts of memory and
    CPU when decompressed by Decrypt or DecryptMulti. Those functions now return an error if the decompressed
    data would exceed 250kB or 10x the compressed size (whichever is larger). This vulnerability has been
    patched in versions 4.0.1, 3.0.3 and 2.6.3. (CVE-2024-28180)

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