SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionPeter Pi discovered a buffer overflow in the virtio network backend (vhost_net) implementation in the Linux kernel. An attacker in a guest may be able to use this to cause a denial of service (host OS crash) or possibly execute arbitrary code in the host OS. (CVE-2019-14835)
It was discovered that the Linux kernel on PowerPC architectures did not properly handle Facility Unavailable exceptions in some situations. A local attacker could use this to expose sensitive information. (CVE-2019-15030)
It was discovered that the Linux kernel on PowerPC architectures did not properly handle exceptions on interrupts in some situations. A local attacker could use this to expose sensitive information.
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
