Ubuntu 16.04 LTS : Linux kernel (Raspberry Pi 2) vulnerabilities (USN-3070-2)

high Nessus Plugin ID 93241

Language:

Synopsis

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

Description

The remote Ubuntu 16.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3070-2 advisory.

 A missing permission check when settings ACLs was discovered in nfsd. A local user could exploit this flaw to gain access to any file by setting an ACL. (CVE-2016-1237)

 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)

 James Patrick-Evans discovered that the airspy USB device driver in the Linux kernel did not properly handle certain error conditions. An attacker with physical access could use this to cause a denial of service (memory consumption). (CVE-2016-5400)

 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)

 It was discovered that the OverlayFS implementation in the Linux kernel did not properly verify dentry state before proceeding with unlink and rename operations. A local attacker could use this to cause a denial of service (system crash). (CVE-2016-6197)

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.
