 Package : netty CVE ID : CVE-2025-55163 CVE-2025-58056 CVE-2025-58057 CVE-2025-59419 CVE-2025-67735 CVE-2024-29025 Debian Bug : 1068110 1111105 1113995 1113994 1118282 1123606

 Several security vulnerabilities have been discovered in Netty, a Java NIO client/server socket framework. 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 for bookworm 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 the oldstable distribution (bookworm), these problems have been fixed in version 1:4.1.48-7+deb12u2.

 For the stable distribution (trixie), these problems have been fixed in version 1:4.1.48-10+deb13u1.

 We recommend that you upgrade your netty packages.
