CVE-2020-25645

Se encontró un fallo en el kernel de Linux en versiones anteriores a 5.9-rc7. El tráfico entre dos endpoints Geneve puede no estar cifrado cuando IPsec está configurado para cifrar el tráfico para el puerto UDP específico usado por el túnel GENEVE, permitiendo a cualquier persona entre los dos endpoints leer el tráfico sin cifrar. La principal amenaza de esta vulnerabilidad es la confidencialidad de los datos

A flaw was found in the Linux kernel. Traffic between two Geneve endpoints may be unencrypted when IPsec is configured to encrypt traffic for the specific UDP port used by the GENEVE tunnel allowing anyone in between the two endpoints to read the traffic unencrypted. The main threat from this vulnerability is to data confidentiality.

It was discovered that a race condition existed in the binder IPC implementation in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Daniele Antonioli, Nils Ole Tippenhauer, and Kasper Rasmussen discovered that legacy pairing and secure-connections pairing authentication in the Bluetooth protocol could allow an unauthenticated user to complete authentication without pairing credentials via adjacent access. A physically proximate attacker could use this to impersonate a previously paired Bluetooth device. Various other issues were also addressed.
