It was found that Netty was vulnerable to the MadeYouReset DDoS attack, a logical vulnerability in the HTTP/2 protocol itself and programming errors which enabled request smuggling attacks. Additionally Netty contained an SMTP command injection vulnerability due to insufficient input validation potentially allowing remote attackers to forge arbitrary emails from trusted servers. The security update also contains the fix for CVE-2024-29025. Julien Viet discovered that Netty was vulnerable to allocation of resources without limits or throttling due to the accumulation of data in the HttpPostRequestDecoder. This would allow an attacker to cause a denial of service. For Debian 11 bullseye, these problems have been fixed in version 1:4.1.48-4+deb11u3. We recommend that you upgrade your netty packages.
