It was discovered that Netty did not properly handle malformed HTTP/2
control frames. An attacker could use this to cause a denial of service
via resource exhaustion. This issue only affects Ubuntu 18.04 LTS,
Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, and Ubuntu 24.04 LTS. (CVE-2025-55163)
It was discovered that Netty did not properly validate the request URI
for line-break characters. An attacker could use this to perform CRLF
injection and request smuggling. (CVE-2025-67735)
