Ubuntu 15.04 : linux vulnerability (USN-2762-1)

medium Nessus Plugin ID 86296

Language:

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

Dmitry Vyukov discovered that the Linux kernel did not properly initialize IPC object state in certain situations. A local attacker could use this to escalate their privileges, expose confidential information, or cause a denial of service (system crash).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected linux-image-3.19-generic, linux-image-3.19-generic-lpae and / or linux-image-3.19-lowlatency packages.
