DESCRIPTION

* CVE-2013-2017: Double free in Virtual Ethernet Tunnel driver (veth).

A double free flaw was found in the Linux kernel's Virtual Ethernet
Tunnel driver (veth). A remote attacker could possibly use this flaw to
crash a target system.


* CVE-2013-1943: Local privilege escalation in KVM memory mappings.

A missing sanity check was found in KVM's memory mapping subsystem,
allowing a user-space process to register memory regions pointing
to the kernel address space. A local, unprivileged user could use this flaw
to escalate their privileges.


* CVE-2013-1935: Denial of service in KVM paravirt interrupt handling.

A flaw was found in the way KVM initialized a guest's registered
paravirtualized end-of-interrupt indication flag when entering the
guest. An unprivileged guest user could potentially use this flaw
to crash the host. (CVE-2013-1935, Important)
