medium Nessus Plugin ID 80514
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote Ubuntu host is missing one or more security-related patches.


A NULL pointer dereference flaw was discovered in the the Linux kernel's SCTP implementation when ASCONF is used. A remote attacker could exploit this flaw to cause a denial of service (system crash) via a malformed INIT chunk. (CVE-2014-7841)

A race condition with MMIO and PIO transactions in the KVM (Kernel Virtual Machine) subsystem of the Linux kernel was discovered. A guest OS user could exploit this flaw to cause a denial of service (guest OS crash) via a specially crafted application. (CVE-2014-7842)

Milos Prchlik reported a flaw in how the ARM64 platform handles a single byte overflow in __clear_user. A local user could exploit this flaw to cause a denial of service (system crash) by reading one byte beyond a /dev/zero page boundary. (CVE-2014-7843)

A stack buffer overflow was discovered in the ioctl command handling for the Technotrend/Hauppauge USB DEC devices driver. A local user could exploit this flaw to cause a denial of service (system crash) or possibly gain privileges. (CVE-2014-8884).

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.


Update the affected linux-image-3.16-generic, linux-image-3.16-generic-lpae and / or linux-image-3.16-lowlatency packages.
