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. 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: https://security-tracker.debian.org/tracker/netty Further information about Debian Security Advisories, how to apply these updates to your system and frequently asked questions can be found at: https://www.debian.org/security/ Mailing list: debian-security-announce@lists.debian.org -----BEGIN PGP SIGNATURE----- iQKTBAEBCgB9FiEErPPQiO8y7e9qGoNf2a0UuVE7UeQFAmVY5TZfFIAAAAAALgAo aXNzdWVyLWZwckBub3RhdGlvbnMub3BlbnBncC5maWZ0aGhvcnNlbWFuLm5ldEFD RjNEMDg4RUYzMkVERUY2QTFBODM1RkQ5QUQxNEI5NTEzQjUxRTQACgkQ2a0UuVE7 UeRHiBAAzFhW85Ho37J02wrSDVwhIMTsVjNO9lnA08Pswdohr9K1wxeCJ/hBAx97 UNIrjTxyOfCJWi1Kj5pITXEHBRu6w1fj/5y9yoMpAKEu+oGQroHbSf4CPmqP2Of0 eamkfbGx2Dh7Ug3qYxe+elcqRtU3gu8I8DYcWJnm2VpWq7/pbNJ+9iqtmMjhkPLH 1etLI/5HAkwpPimZSrHzcimn39gEVaIbZLc86ZBAoAPghc+iJR1JFHERmkEutWkB eAnL3kD1mr6F711eZvDfPaRfEUVorW67ZEpPX68MJExuYHNXd268EhQOhf/ZYv8g SUSBJuKw4w2OnL4fn8lhqnQgYHUVkcYBtfYii6E9bEVAIPoaT+4gvdSg9zkF6cza Da8SXkEY2ysaX+A24iVnCNMpCMSOUOxWsFFvkCcfi8A4HxGGqWzVOsBbDJKjktS1 g6FyeqWsGh9QG/CPYeMN7LB7lW1l2XzO6GQ9QR1rzU/whgUVxprkye5wx2BaQmom rrWVHBijH1cNWd1IbryAm+prduL1l/CNR0785ZPTjB3SsMFPCAtRHf9G976rqVs0 P3jGg+BdeDj+sd3EFHcHnNXQOaETgR07RWzngbjEkgmJYhB2B43hCQ2LwsNlHsmg O6otUI2k274IF9KHh0T1h1hopbUTU8VPy3dpcLloCzk7KiAv1RI= =4ExT -----END PGP SIGNATURE----- . ========================================================================== Ubuntu Security Notice USN-6754-2 May 07, 2024 nghttp2 vulnerability ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 24.04 LTS Summary: Several security issues were fixed in nghttp2.
