"The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are
affected by a vulnerability as referenced in the SUSE-SU-2024:1079-1 advisory.

  - Netty is an asynchronous event-driven network application framework for rapid development of maintainable
    high performance protocol servers & clients. The `HttpPostRequestDecoder` can be tricked to accumulate
    data. While the decoder can store items on the disk if configured so, there are no limits to the number of
    fields the form can have, an attacher can send a chunked post consisting of many small fields that will be
    accumulated in the `bodyListHttpData` list. The decoder cumulates bytes in the `undecodedChunk` buffer
    until it can decode a field, this field can cumulate data without limits. This vulnerability is fixed in
    4.1.108.Final. (CVE-2024-29025)

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