USN-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. (CVE-2018-13053)

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 (system crash). (CVE-2018-13093)

Wen Xu discovered that the f2fs file system implementation in the Linux kernel did not properly validate metadata. An attacker could use this to construct a malicious f2fs image that, when mounted, could cause a denial of service (system crash). (CVE-2018-13096, CVE-2018-13097, CVE-2018-13098, CVE-2018-13099, CVE-2018-13100, CVE-2018-14614, CVE-2018-14615, CVE-2018-14616)

Wen Xu and Po-Ning Tseng discovered that btrfs file system implementation in the Linux kernel did not properly validate metadata. An attacker could use this to construct a malicious btrfs image that, when mounted, could cause a denial of service (system crash). (CVE-2018-14609, CVE-2018-14610, CVE-2018-14611, CVE-2018-14612, CVE-2018-14613)

Wen Xu discovered that the HFS+ filesystem implementation in the Linux kernel did not properly handle malformed catalog data in some situations. An attacker could use this to construct a malicious HFS+ image that, when mounted, could cause a denial of service (system crash). (CVE-2018-14617)

Vasily Averin and Pavel Tikhomirov discovered that the cleancache subsystem of the Linux kernel did not properly initialize new files in some situations. A local attacker could use this to expose sensitive information. (CVE-2018-16862)

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 (system crash). (CVE-2018-19985)
