| Description: | Summary:
The remote host is missing an update for the 'linux, linux-aws, linux-kvm, linux-lts-xenial, linux-raspi2, linux-snapdragon' package(s) announced via the USN-4579-1 advisory.
Vulnerability Insight:
Hadar Manor discovered that the DCCP protocol implementation in the Linux
kernel improperly handled socket reuse, leading to a use-after-free
vulnerability. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2020-16119)
Wen Xu discovered that the XFS file system in the Linux kernel did not
properly validate inode metadata in some situations. An attacker could use
this to construct a malicious XFS image that, when mounted, could cause a
denial of service (system crash). (CVE-2018-10322)
Jay Shin discovered that the ext4 file system implementation in the Linux
kernel did not properly handle directory access with broken indexing,
leading to an out-of-bounds read vulnerability. A local attacker could use
this to cause a denial of service (system crash). (CVE-2020-14314)
It was discovered that a race condition existed in the hugetlb sysctl
implementation in the Linux kernel. A privileged attacker could use this to
cause a denial of service (system crash). (CVE-2020-25285)
