| Beschreibung: | Summary:
The remote host is missing an update for the 'linux'
package(s) announced via the USN-4094-1 advisory.
Vulnerability Insight:
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 ...
