Ubuntu 16.04 LTS : Linux kernel regression (USN-3392-1)

high Nessus Plugin ID 102524

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-3392-1 advisory.

 USN-3378-1 fixed vulnerabilities in the Linux kernel. Unfortunately, a regression was introduced that prevented conntrack from working correctly in some situations. This update fixes the problem.

 We apologize for the inconvenience.

 Original advisory details:

 Fan Wu and Shixiong Zhao discovered a race condition between inotify events

 and vfs rename operations in the Linux kernel. An unprivileged local

 attacker could use this to cause a denial of service (system crash) or

 execute arbitrary code. (CVE-2017-7533)

 It was discovered that the Linux kernel did not properly restrict

 RLIMIT_STACK size. A local attacker could use this in conjunction with

 another vulnerability to possibly execute arbitrary code.

 (CVE-2017-1000365)

 discovered that the Virtio GPU driver in the Linux kernel did not

 properly free memory in some situations. A local attacker could use this to

 cause a denial of service (memory consumption). (CVE-2017-10810)

 discovered that the RxRPC Kerberos 5 ticket handling code in the

 Linux kernel did not properly verify metadata. A remote attacker could use

 this to cause a denial of service (system crash) or possibly execute

 arbitrary code. (CVE-2017-7482)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel package.
