Details

Two security vulnerabilities have been discovered in Netty, a Java NIO client/server socket framework.

• CVE-2023-34462 It might be possible for a remote peer to send a client hello packet during a TLS handshake which lead the server to buffer up to 16 MB of data per connection. This could lead to a OutOfMemoryError and so result in a denial of service.
• CVE-2023-44487 The HTTP/2 protocol allowed a denial of service (server resource consumption) because request cancellation can reset many streams quickly. This problem is also known as Rapid Reset Attack.

For the oldstable distribution (bullseye), these problems have been fixed in version 1:4.1.48-4+deb11u2.

For the stable distribution (bookworm), these problems have been fixed in version 1:4.1.48-7+deb12u1.

We recommend that you upgrade your netty packages.
