[USN-4578-1] Linux kernel vulnerabilities

Severity High
Affected Packages 58
CVEs 7
Info Packages Vulnerabilities

Several security issues were fixed in the Linux kernel.

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)

It was discovered that the btrfs file system in the Linux kernel contained
a use-after-free vulnerability when merging free space. An attacker could
use this to construct a malicious btrfs image that, when mounted and
operated on, could cause a denial of service (system crash).
(CVE-2019-19448)

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)

Giuseppe Scrivano discovered that the overlay file system in the Linux
kernel did not properly perform permission checks in some situations. A
local attacker could possibly use this to bypass intended restrictions and
gain read access to restricted files. (CVE-2020-16120)

It was discovered that the NFS client implementation in the Linux kernel
did not properly perform bounds checking before copying security labels in
some situations. A local attacker could use this to cause a denial of
service (system crash) or possibly execute arbitrary code. (CVE-2020-25212)

It was discovered that the NFC implementation in the Linux kernel did not
properly perform permissions checks when opening raw sockets. A local
attacker could use this to create or listen to NFC traffic.
(CVE-2020-26088)
