Ubuntu 14.04 LTS : Linux kernel (Utopic HWE) regression (USN-2948-2)

critical Nessus Plugin ID 90507

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 14.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-2948-2 advisory.

 USN-2948-1 fixed vulnerabilities in the Ubuntu 14.10 Linux kernel backported to Ubuntu 14.04 LTS. An incorrect reference counting fix in the radeon driver introduced a regression that could cause a system crash. This update fixes the problem.

 We apologize for the inconvenience.

 Original advisory details:

 Ralf Spenneberg discovered that the USB driver for Clie devices in the

 Linux kernel did not properly validate the endpoints reported by the

 device. An attacker with physical access could cause a denial of service

 (system crash). (CVE-2015-7566)

 Ralf Spenneberg discovered that the usbvision driver in the Linux kernel

 did not properly validate the interfaces and endpoints reported by the

 device. An attacker with physical access could cause a denial of service

 (system crash). (CVE-2015-7833)

 Venkatesh Pottem discovered a use-after-free vulnerability in the Linux

 kernel's CXGB3 driver. A local attacker could use this to cause a denial of

 service (system crash) or possibly execute arbitrary code. (CVE-2015-8812)

 It was discovered that a race condition existed in the ioctl handler for

 the TTY driver in the Linux kernel. A local attacker could use this to

 cause a denial of service (system crash) or expose sensitive information.

 (CVE-2016-0723)

 Xiaofei Rex Guo discovered a timing side channel vulnerability in the Linux

 Extended Verification Module (EVM). An attacker could use this to affect

 system integrity. (CVE-2016-2085)

 David Herrmann discovered that the Linux kernel incorrectly accounted file

 descriptors to the original opener for in-flight file descriptors sent over

 a unix domain socket. A local attacker could use this to cause a denial of

 service (resource exhaustion). (CVE-2016-2550)

 Ralf Spenneberg discovered that the USB driver for Treo devices in the

 Linux kernel did not properly validate the endpoints reported by the

 device. An attacker with physical access could cause a denial of service

 (system crash). (CVE-2016-2782)

 It was discovered that the Linux kernel did not enforce limits on the

 amount of data allocated to buffer pipes. A local attacker could use this

 to cause a denial of service (resource exhaustion). (CVE-2016-2847)

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.
