Ubuntu 14.04 LTS : Linux kernel vulnerabilities (USN-3071-1)

high Nessus Plugin ID 93218

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-3071-1 advisory.

Kangjie Lu discovered an information leak in the Reliable Datagram Sockets (RDS) implementation in the Linux kernel. A local attacker could use this to obtain potentially sensitive information from kernel memory. (CVE-2016-5244)

Yue Cao et al discovered a flaw in the TCP implementation's handling of challenge acks in the Linux kernel. A remote attacker could use this to cause a denial of service (reset connection) or inject content into an TCP stream. (CVE-2016-5696)

Pengfei Wang discovered a race condition in the MIC VOP driver in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or obtain potentially sensitive information from kernel memory. (CVE-2016-5728)

Cyril Bur discovered that on PowerPC platforms, the Linux kernel mishandled transactional memory state on exec(). A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2016-5828)

It was discovered that a heap based buffer overflow existed in the USB HID driver in the Linux kernel. A local attacker could use this cause a denial of service (system crash) or possibly execute arbitrary code.
(CVE-2016-5829)

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.
