Ubuntu Security Notice USN-4752-1
Posted Feb 25, 2021
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 4752-1 - 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. Jay Shin discovered that the ext4 file system implementation in the Linux kernel did not properly handle directory access with broken indexing, leading to an out-of-bounds read vulnerability. A local attacker could use this to cause a denial of service. Various other issues were also addressed.

Ubuntu Security Notice USN-4659-2
Posted Dec 14, 2020
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 4659-2 - USN-4659-1 fixed vulnerabilities in the Linux kernel. Unfortunately, that update introduced a regression in the software raid10 driver when used with fstrim that could lead to data corruption. This update fixes the problem. 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. Various other issues were also addressed.
