[USN-4116-1] Linux kernel vulnerabilities

Severity Medium
Affected Packages 55
CVEs 6
Info Packages Vulnerabilities

Several security issues were fixed in the Linux kernel.

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)

Amit Klein and Benny Pinkas discovered that the Linux kernel did not
sufficiently randomize IP ID values generated for connectionless networking
protocols. A remote attacker could use this to track particular Linux
devices. (CVE-2019-10638)

Praveen Pandey discovered that the Linux kernel did not properly validate
sent signals in some situations on PowerPC systems with transactional
memory disabled. A local attacker could use this to cause a denial of
service. (CVE-2019-13648)

It was discovered that the floppy driver in the Linux kernel did not
properly validate meta data, leading to a buffer overread. A local attacker
could use this to cause a denial of service (system crash).
(CVE-2019-14283)

It was discovered that the floppy driver in the Linux kernel did not
properly validate ioctl() calls, leading to a division-by-zero. A local
attacker could use this to cause a denial of service (system crash).
(CVE-2019-14284)

Jason Wang discovered that an infinite loop vulnerability existed in the
virtio net driver in the Linux kernel. A local attacker in a guest VM could
possibly use this to cause a denial of service in the host system.
(CVE-2019-3900)
