8ab9a27f59391b5775c4114cc28e1e91a71bab3ef9b57e5d9b1cb360a669e9f5Ubuntu 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.

3699f63fe43f86e6c44ae89e57ff19c771763fa6ea9bef8f89f0a03e12ce9ae8Ubuntu Security Notice 4578-1 - Hador Manor discovered that the DCCP protocol implementation in the Linux kernel improperly handled socket reuse, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Wen Xu discovered that the XFS file system in the Linux kernel did not properly validate inode metadata in some situations. An attacker could use this to construct a malicious XFS image that, when mounted, could cause a denial of service. Various other issues were also addressed.
