Package        : netty
CVE ID         : CVE-2023-34462 CVE-2023-44487
Debian Bug     : 1038947 1054234
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.
For the detailed security status of netty please refer to
its security tracker page at:
