Ubuntu 15.04 : linux vulnerabilities (USN-2829-1)

Medium Nessus Plugin ID 87216

Synopsis

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

Description

It was discovered that the SCTP protocol implementation in the Linux kernel performed an incorrect sequence of protocol-initialization steps. A local attacker could use this to cause a denial of service (system crash). (CVE-2015-5283)

Dmitry Vyukov discovered that the Linux kernel's keyring handler attempted to garbage collect incompletely instantiated keys. A local unprivileged attacker could use this to cause a denial of service (system crash). (CVE-2015-7872).

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.
