Debian DSA-2396-1 : qemu-kvm - buffer underflow

high Nessus Plugin ID 57736

Language:

Synopsis

The remote Debian host is missing a security-related update.

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.

Solution

Upgrade the qemu-kvm packages.

For the stable distribution (squeeze), this problem has been fixed in version 0.12.5+dfsg-5+squeeze8.
