CVE Author: NIST National Vulnerability Database (NVD)

CVSS Base Vector:
AV:A/AC:L/Au:N/C:C/I:C/A:C

Summary:
The remote host is missing an update for the 'linux' Linux Distribution Package(s) announced via the USN-4094-1 advisory.

Detection Method:
Checks if a vulnerable Linux Distribution Package version is present on the target host.

Technical Details:
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) 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-2018-13097, CVE-2018-13099, CVE-2018-13100, CVE-2018-14614, CVE-2018-14616, CVE-2018-13096, CVE-2018-13098, CVE-2018-14615) 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-2018-14610, CVE-2018-14611, CVE-2018-14612, CVE-2018-14613, CVE-2018-14609) 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 USB subsystem in the Linux kernel did not properly handle size checks when handling an extra USB descriptor. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2018-20169) It was discovered that a use-after-free error existed in the block layer subsystem of the Linux kernel when certain failure conditions occurred. A local attacker could possibly use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-20856) 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. (CVE-2018-5383) It was discovered that a heap buffer overflow existed in the Marvell Wireless ... Description truncated.
