Detail
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: Ubuntu 10.04 LTS: Ubuntu 10.10: 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. |
