Summary
netty vulnerabilities
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)
