Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS / 25.04 / 25.10 : Netty vulnerabilities (USN-7918-1)

medium Nessus Plugin ID 278078

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

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)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

Solution

Update the affected libnetty-java package.
