Debian: DSA-5316-1 Critical Netty Security Update: DoS Risks

Several out-of-memory, stack overflow or HTTP request smuggling vulnerabilities
have been discovered in Netty, a Java NIO client/server socket framework, which
may allow attackers to cause a denial of service or bypass restrictions when
used as a proxy.

For the stable distribution (bullseye), these problems have been fixed in
version 1:4.1.48-4+deb11u1.

We recommend that you upgrade your netty packages.

For the detailed security status of netty please refer to
