Debian Bug : 1027180 1014769 1001437
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 Debian 10 buster, these problems have been fixed in version
1:4.1.33-1+deb10u3.
We recommend that you upgrade your netty packages.
For the detailed security status of netty please refer to
