Ubuntu 12.04 LTS : linux-lts-trusty vulnerabilities (USN-2826-1)

Medium Nessus Plugin ID 87203


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


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.


Update the affected linux-image-3.13-generic and / or linux-image-3.13-generic-lpae packages.
