[USN-2589-1] Linux kernel (Utopic HWE) vulnerabilities

Severity Medium
Affected Packages 8
CVEs 4
Info Packages Vulnerabilities

Several security issues were fixed in the kernel.

Jan Beulich discovered the Xen virtual machine subsystem of the Linux
kernel did not properly restrict access to PCI command registers. A local
guest user could exploit this flaw to cause a denial of service (host
crash). (CVE-2015-2150)

A stack overflow was discovered in the the microcode loader for the intel
x86 platform. A local attacker could exploit this flaw to cause a denial of
service (kernel crash) or to potentially execute code with kernel
privileges. (CVE-2015-2666)

A privilege escalation was discovered in the fork syscall via the int80
entry on 64 bit kernels with 32 bit emulation support. An unprivileged
local attacker could exploit this flaw to increase their privileges on the
system. (CVE-2015-2830)

It was discovered that the Linux kernel's IPv6 networking stack has a flaw
that allows using route advertisement (RA) messages to set the 'hop_limit'
to values that are too low. An unprivileged attacker on a local network
could exploit this flaw to cause a denial of service (IPv6 messages
dropped). (CVE-2015-2922)
