Netty is an asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. In netty-codec-compression versions 4.1.124.Final and below, and netty-codec versions 4.2.4.Final and below, when supplied with specially crafted input, BrotliDecoder and certain other decompression decoders will allocate a large number of reachable byte buffers, which can lead to denial of service. BrotliDecoder.decompress has no limit in how often it calls pull, decompressing data 64K bytes at a time. The buffers are saved in the output list, and remain reachable until OOM is hit. This is fixed in versions 4.1.125.Final of netty-codec and 4.2.5.Final of netty-codec-compression.

According to its self-reported version number, the Oracle GoldenGate for Big Data application located on the remote host is affected by multiple vulnerabilities:

  - Improper input validation in JDBC Driver for SQL Server allows an unauthorized attacker to perform spoofing over a network.
    (CVE-2025-59250)

  - Uncontrolled Resource Consumption vulnerability in Apache Commons IO. The org.apache.commons.io.input.XmlStreamReader class     may excessively consume CPU resources when processing maliciously crafted input. (CVE-2024-47554)

  - Netty is an asynchronous event-driven network application framework for development of maintainable high performance protocol     servers and clients. In versions 4.1.124.Final, and 4.2.0.Alpha3 through 4.2.4.Final, Netty incorrectly accepts standalone newline     characters (LF) as a chunk-size line terminator, regardless of a preceding carriage return (CR), instead of requiring CRLF per     HTTP/1.1 standards. When combined with reverse proxies that parse LF differently (treating it as part of the chunk extension),     attackers can craft requests that the proxy sees as one request but Netty processes as two, enabling request smuggling attacks.     (CVE-2025-58056)

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

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS / 25.04 / 25.10 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-7918-1 advisory.

    Jeppe Bonde Weikop discovered that Netty incorrectly parsed HTTP messages. When Netty is used with certain     reverse proxies, a remote attacker could possibly use this issue to perform HTTP request smuggling     attacks. (CVE-2025-58056)

    Jonas Konrad discovered that Netty did not properly manage memory when decoding compressed data. A remote     attacker could possibly use this issue to cause Netty to consume excessive memory, resulting in a denial     of service. This issue was only addressed in Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, Ubuntu     24.04 LTS, Ubuntu 25.04, and Ubuntu 25.10. (CVE-2025-58057)

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2025:03114-1 advisory.
