The Linux kernel could be made to run unauthorized programs with administrator privileges.
Nelson Elhage discovered several problems with the Acorn Econet protocol driver. A local user could cause a denial of service via a NULL pointer dereference, escalate privileges by overflowing the kernel stack, and assign Econet addresses to arbitrary interfaces. (CVE-2010-3848, CVE-2010-3849, CVE-2010-3850)

A security issue affects these releases of Ubuntu and its derivatives:
The Linux kernel could be made to run unauthorized programs with administrator privileges.
Nelson Elhage discovered several problems with the Acorn Econet protocol driver. A local user could cause a denial of service via a NULL pointer dereference, escalate privileges by overflowing the kernel stack, and assign Econet addresses to arbitrary interfaces. (CVE-2010-3848, CVE-2010-3849, CVE-2010-3850)
Brad Spengler discovered that the wireless extensions did not correctly validate certain request sizes. A local attacker could exploit this to read portions of kernel memory, leading to a loss of privacy. (CVE-2010-2955)
Dan Rosenberg discovered that the VIA video driver did not correctly clear kernel memory. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy. (CVE-2010-4082)
A flaw was discovered in the Linux kernel’s splice system call. A local user could use this flaw to cause a denial of service (system crash). (CVE-2013-2128)
