Ubuntu 14.04 LTS : Linux kernel vulnerabilities (USN-2226-1)

medium Nessus Plugin ID 74214

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-2226-1 advisory.

 Matthew Daley reported an information leak in the floppy disk driver of the Linux kernel. An unprivileged local user could exploit this flaw to obtain potentially sensitive information from kernel memory.
 (CVE-2014-1738)

 Matthew Daley reported a flaw in the handling of ioctl commands by the floppy disk driver in the Linux kernel. An unprivileged local user could exploit this flaw to gain administrative privileges if the floppy disk module is loaded. (CVE-2014-1737)

 A flaw was discovered in the handling of network packets when mergeable buffers are disabled for virtual machines in the Linux kernel. Guest OS users may exploit this flaw to cause a denial of service (host OS crash) or possibly gain privilege on the host OS. (CVE-2014-0077)

 Trk Edwin discovered a flaw with Xen netback driver when used with Linux configurations that do not allow sleeping in softirq context. A guest administrator could exploit this flaw to cause a denial of service (system crash) on the host. (CVE-2014-2580)

 A flaw was discovered in the Linux kernel's ping sockets. An unprivileged local user could exploit this flaw to cause a denial of service (system crash) or possibly gain privileges via a crafted application.
 (CVE-2014-2851)

 Hannes Frederic Sowa reported a hash collision ordering problem in the xfs filesystem in the Linux kernel.
 A local user could exploit this flaw to cause filesystem corruption and a denial of service (oops or panic). (CVE-2014-7283)

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.
