Ubuntu 16.10 : linux, linux-meta vulnerabilities (USN-3326-1) (Stack Clash)

high Nessus Plugin ID 100924

Synopsis

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

Description

It was discovered that a use-after-free flaw existed in the filesystem encryption subsystem in the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2017-7374)

It was discovered that the stack guard page for processes in the Linux kernel was not sufficiently large enough to prevent overlapping with the heap. An attacker could leverage this with another vulnerability to execute arbitrary code and gain administrative privileges (CVE-2017-1000364)

Roee Hay discovered that the parallel port printer driver in the Linux kernel did not properly bounds check passed arguments. A local attacker with write access to the kernel command line arguments could use this to execute arbitrary code. (CVE-2017-1000363)

Ingo Molnar discovered that the VideoCore DRM driver in the Linux kernel did not return an error after detecting certain overflows. A local attacker could exploit this issue to cause a denial of service (OOPS). (CVE-2017-5577)

A double free bug was discovered in the IPv4 stack of the Linux kernel. An attacker could use this to cause a denial of service (system crash). (CVE-2017-8890)

Andrey Konovalov discovered an IPv6 out-of-bounds read error in the Linux kernel's IPv6 stack. A local attacker could cause a denial of service or potentially other unspecified problems. (CVE-2017-9074)

Andrey Konovalov discovered a flaw in the handling of inheritance in the Linux kernel's IPv6 stack. A local user could exploit this issue to cause a denial of service or possibly other unspecified problems.
(CVE-2017-9075)

It was discovered that dccp v6 in the Linux kernel mishandled inheritance. A local attacker could exploit this issue to cause a denial of service or potentially other unspecified problems.
(CVE-2017-9076)

It was discovered that the transmission control protocol (tcp) v6 in the Linux kernel mishandled inheritance. A local attacker could exploit this issue to cause a denial of service or potentially other unspecified problems. (CVE-2017-9077)

It was discovered that the IPv6 stack was doing over write consistency check after the data was actually overwritten. A local attacker could exploit this flaw to cause a denial of service (system crash).
(CVE-2017-9242).

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.

Solution
