-------------------------------------------------------------------------

Package : netty Version : 1:4.1.33-1+deb10u3 CVE ID : CVE-2021-37136 CVE-2021-37137 CVE-2021-43797 CVE-2022-41881 CVE-2022-41915 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 its security tracker page at:
