Ubuntu 14.04 LTS : Linux kernel vulnerabilities (USN-3127-1)

high Nessus Plugin ID 94731

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3127-1 advisory.

 It was discovered that the compression handling code in the Advanced Linux Sound Architecture (ALSA) subsystem in the Linux kernel did not properly check for an integer overflow. A local attacker could use this to cause a denial of service (system crash). (CVE-2014-9904)

 Kirill A. Shutemov discovered that memory manager in the Linux kernel did not properly handle anonymous pages. A local attacker could use this to cause a denial of service or possibly gain administrative privileges. (CVE-2015-3288)

 Vitaly Kuznetsov discovered that the Linux kernel did not properly suppress hugetlbfs support in X86 paravirtualized guests. An attacker in the guest OS could cause a denial of service (guest system crash).
 (CVE-2016-3961)

 Ondrej Kozina discovered that the keyring interface in the Linux kernel contained a buffer overflow when displaying timeout events via the /proc/keys interface. A local attacker could use this to cause a denial of service (system crash). (CVE-2016-7042)

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

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

Solution

Update the affected kernel package.
