Description

Nicolae Mogoreanu discovered a heap overflow in the emulated e1000e network interface card of KVM, a solution for full virtualization on x86 hardware, which could result in denial of service or privilege escalation.

This update also fixes a guest-triggerable memory corruption in VNC handling.
