Ubuntu Security Notice 3678-4 - Wen Xu discovered that the ext4 filesystem implementation in the Linux kernel did not properly handle corrupted meta data in some situations. An attacker could use this to specially craft an ext4 file system that caused a denial of service when mounted. It was discovered that the 802.11 software simulator implementation in the Linux kernel contained a memory leak when handling certain error conditions. A local attacker could possibly use this to cause a denial of service. Various other issues were also addressed.

b71a6729238f35ec13634f2c220c34d3Ubuntu Security Notice 3680-1 - Ken Johnson and Jann Horn independently discovered that microprocessors utilizing speculative execution of a memory read may allow unauthorized memory reads via sidechannel attacks. An attacker in the guest could use this to expose sensitive guest information, including kernel memory. This update allows libvirt to expose new CPU features added by microcode updates to guests. Daniel P. Berrange discovered that libvirt incorrectly handled the QEMU guest agent. An attacker could possibly use this issue to consume resources, leading to a denial of service. Various other issues were also addressed.
