- netty - event-driven asynchronous network application framework
Details
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)
