CVE-2021-21409

TITLE

Debian Security Advisory 4885-1

DESCRIPTION

Netty is an open-source, asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. In Netty (io.netty:netty-codec-http2) before version 4.1.61.Final there is a vulnerability that enables request smuggling. The content-length header is not correctly validated if the request only uses a single Http2HeaderFrame with the endStream set to to true. This could lead to request smuggling if the request is proxied to a remote peer and translated to HTTP/1.1. This is a followup of GHSA-wm47-8v5p-wjpj/CVE-2021-21295 which did miss to fix this one case. This was fixed as part of 4.1.61.Final. For the stable distribution (buster), these problems have been fixed in version 1:4.1.33-1+deb10u2. We recommend that you upgrade your netty packages. For the detailed security status of netty please refer to its security tracker page at: https://security-tracker.debian.org/tracker/netty Further information about Debian Security Advisories, how to apply these updates to your system and frequently asked questions can be found at: https://www.debian.org/security/ Mailing list: debian-security-announce@lists.debian.org -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEEtuYvPRKsOElcDakFEMKTtsN8TjYFAmBrXn0ACgkQEMKTtsN8 TjYiIQ/+M3dHpXdXRxZlx12OSJNsJoZa52/7uKhM9Vg0HhdCYnq7RjXTI2zZmUu7 VbL/F1ixPFgHWZpFIwHPTxZ4qk5+qQKYj7JyU1g+NyL9MkVsAW7ccYj3gbp3Kgk6 bE2GEwfh0qSKDgolflLCudGsqF1J54T65kO5oQ+Gtbx/8+NJ0YrVrHsmG1O4IMHQ 6oK/znY6CmQtUSY1p8DCNTWp63hZYpGzg9Umv/y9TaYm3QeG1BNz3tQz8uaGZQWq LihkaTSpJoo7ezNUFYinaRECylpEf7MHgK+uYkJ0MZrZ+2wyMC6V0BATVwF2Aj7X VMrRBJTSf20z5u/k0m+y9k8cR8CcR3sWVo/7mpRJAIsvnyMQwKBmxjHSlVfzOqYK 91NB7OSi/ZDKOOsdQ5oW337FPQolCXl2DOe2UW9Z1K9XFs11VplsFxMkrzZtiwba dXhq6odVZwQfzjiWGj0yFftfJSAAs9B0I1L1EqW2QR7sN25YA1OosYsc5iYvUXD7 mhjU1RtqsXK3jI9TjGmXos+6Yj36iPncNwXBL4AKKPapV5qm6mHQkXTowW1NM5vu 8NokTjKtuixgb08CAQHNe202TpQ9kGHNTe2FDKRNFQrlTaoxt2DlmHbDiLn6i1Ue k4HImGqrUw9venxQ/vPZjTW6UaTbz0D9BPQcb9ApBOAgydEjJqE= =6i6I -----END PGP SIGNATURE----- .
