a0f2e867941fc69f77f5654ca781bae3Ubuntu Security Notice 4115-2 - USN 4115-1 fixed vulnerabilities in the Linux 4.15 kernel for Ubuntu 18.04 LTS and Ubuntu 16.04 LTS. Unfortunately, as part of the update, a regression was introduced that caused a kernel crash when handling fragmented packets in some situations. This update addresses the issue. Various other issues were also addressed.
f3c403ca6993818b3a6b46a2dc892b23Ubuntu Security Notice 4118-1 - It was discovered that the alarmtimer implementation in the Linux kernel contained an integer overflow vulnerability. A local attacker could use this to cause a denial of service. Wen Xu discovered that the XFS filesystem implementation in the Linux kernel did not properly track inode validations. 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.
606239d761ad7f615ccb6ead5cc82c96Ubuntu Security Notice 4115-1 - Hui Peng and Mathias Payer discovered that the Option USB High Speed driver in the Linux kernel did not properly validate metadata received from the device. A physically proximate attacker could use this to cause a denial of service. Zhipeng Xie discovered that an infinite loop could triggered in the CFS Linux kernel process scheduler. A local attacker could possibly use this to cause a denial of service. Various other issues were also addressed.
d33b91a9062e22127c5fc65115ec33feUbuntu Security Notice 4095-1 - Eli Biham and Lior Neumann discovered that the Bluetooth implementation in the Linux kernel did not properly validate elliptic curve parameters during Diffie-Hellman key exchange in some situations. An attacker could use this to expose sensitive information. It was discovered that a heap buffer overflow existed in the Marvell Wireless LAN device driver for the Linux kernel. An attacker could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.
