Ubuntu 14.04 LTS : Linux kernel vulnerabilities (USN-2794-1)

high Nessus Plugin ID 86785

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-2794-1 advisory.

 It was discovered that in certain situations, a directory could be renamed outside of a bind mounted location. An attacker could use this to escape bind mount containment and gain access to sensitive information. (CVE-2015-2925)

 Moein Ghasemzadeh discovered that the USB WhiteHEAT serial driver contained hardcoded attributes about the USB devices. An attacker could construct a fake WhiteHEAT USB device that, when inserted, causes a denial of service (system crash). (CVE-2015-5257)

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.
