Ubuntu: New QEMU packages fix security vulnerabilities

Neil Wilson discovered that if VNC passwords were blank in QEMU configurations, access to VNC sessions was allowed without a password instead of being disabled. A remote attacker could connect to running VNC sessions of QEMU and directly control the system. By default, QEMU does not start VNC sessions. Updated packages are available from security.ubuntu.com.

===========================================================
Ubuntu Security Notice USN-1063-1 February 14, 2011
qemu-kvm vulnerability
CVE-2011-0011
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 9.10
Ubuntu 10.04 LTS
Ubuntu 10.10

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 9.10:
kvm 0.11.0-0ubuntu6.4
qemu 0.11.0-0ubuntu6.4
qemu-arm-static 0.11.0-0ubuntu6.4
qemu-kvm 0.11.0-0ubuntu6.4
qemu-kvm-extras 0.11.0-0ubuntu6.4

Ubuntu 10.04 LTS:
kvm 0.12.3+noroms-0ubuntu9.4
qemu 0.12.3+noroms-0ubuntu9.4
qemu-arm-static 0.12.3+noroms-0ubuntu9.4
qemu-common 0.12.3+noroms-0ubuntu9.4
qemu-kvm 0.12.3+noroms-0ubuntu9.4
qemu-kvm-extras 0.12.3+noroms-0ubuntu9.4
qemu-kvm-extras-static 0.12.3+noroms-0ubuntu9.4

Ubuntu 10.10:
kvm 0.12.5+noroms-0ubuntu7.2
qemu 0.12.5+noroms-0ubuntu7.2
qemu-arm-static 0.12.5+noroms-0ubuntu7.2
qemu-kvm 0.12.5+noroms-0ubuntu7.2
qemu-kvm-extras 0.12.5+noroms-0ubuntu7.2
qemu-kvm-extras-static 0.12.5+noroms-0ubuntu7.2

After a standard system update you need to restart any running QEMU sessions
to make all the necessary changes.

Details follow:

Neil Wilson discovered that if VNC passwords were blank in QEMU
configurations, access to VNC sessions was allowed without a password
instead of being disabled. A remote attacker could connect to running
VNC sessions of QEMU and directly control the system. By default, QEMU
does not start VNC sessions.
