Ubuntu 14.04 LTS : Linux kernel vulnerabilities (USN-2663-1)

high Nessus Plugin ID 84614

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-2663-1 advisory.

 Alexandre Oliva reported a race condition flaw in the btrfs file system's handling of extended attributes (xattrs). A local attacker could exploit this flaw to bypass ACLs and potentially escalate privileges.
 (CVE-2014-9710)

 A race condition was discovered in the Linux kernel's file_handle size verification. A local user could exploit this flaw to read potentially sensative memory locations. (CVE-2015-1420)

 A underflow error was discovered in the Linux kernel's Ozmo Devices USB over WiFi host controller driver.
 A remote attacker could exploit this flaw to cause a denial of service (system crash) or potentially execute arbitrary code via a specially crafted packet. (CVE-2015-4001)

 A bounds check error was discovered in the Linux kernel's Ozmo Devices USB over WiFi host controller driver. A remote attacker could exploit this flaw to cause a denial of service (system crash) or potentially execute arbitrary code via a specially crafted packet. (CVE-2015-4002)

 A division by zero error was discovered in the Linux kernel's Ozmo Devices USB over WiFi host controller driver. A remote attacker could exploit this flaw to cause a denial of service (system crash).
 (CVE-2015-4003)

 Carl H Lunde discovered missing consistency checks in the Linux kernel's UDF file system (CONFIG_UDF_FS).
 A local attacker could exploit this flaw to cause a denial of service (system crash) by using a corrupted file system image. (CVE-2015-4167)

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.
