[USN-1023-1] Linux kernel vulnerabilities

Severity Medium

CVEs 6

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).
