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.
