Rogue VNC clients could make the built in VNC server of kvm run into an infinite loop (CVE-2008-2382)

An off-by-one bug limited the length of VNC passwords to seven instead of eight (CVE-2008-5714)

Virtualized guests could potentially execute code on the host by triggering a buffer overflow in the network emulation code via large ethernet frames (CVE-2007-5729)

Virtualized guests could potentially execute code on the host by triggering a heap based buffer overflow in the Cirrus Graphics card emulation (CVE-2007-1320).

USN-776-1 fixed vulnerabilities in KVM. Due to an incorrect fix, a regression was introduced in Ubuntu 8.04 LTS that caused KVM to fail to boot virtual machines started via libvirt. This update fixes the problem. We apologize for the inconvenience.

Avi Kivity discovered that KVM did not correctly handle certain disk formats. A local attacker could attach a malicious partition that would allow the guest VM to read files on the VM host. (CVE-2008-1945, CVE-2008-2004)

Alfredo Ortega discovered that KVM's VNC protocol handler did not correctly validate certain messages. A remote attacker could send specially crafted VNC messages that would cause KVM to consume CPU resources, leading to a denial of service. (CVE-2008-2382)

Jan Niehusmann discovered that KVM's Cirrus VGA implementation over VNC did not correctly handle certain bitblt operations. A local attacker could exploit this flaw to potentially execute arbitrary code on the VM host or crash KVM, leading to a denial of service. (CVE-2008-4539)

It was discovered that KVM's VNC password checks did not use the correct length. A remote attacker could exploit this flaw to cause KVM to crash, leading to a denial of service.
(CVE-2008-5714).

qemu update to version 0.10.1 fixes the following security issues :

CVE-2008-0928: problems with range checks of block devices CVE-2008-1945: problems with removable media handling CVE-2008-2382:
vnc server DoS CVE-2008-4539: fix a heap overflow in the cirrus VGA implementation CVE-2008-5714: off by one error in vnc password handling

A security vulnerability have been discovered and corrected in VNC server of qemu 0.9.1 and earlier, which could lead to a denial-of-service attack (CVE-2008-2382).

The updated packages have been patched to prevent this.

Paul Szabo discovered that the DECRQSS escape sequences were not handled correctly by xterm. Additionally, window title operations were also not safely handled. If a user were tricked into viewing a specially crafted series of characters while in xterm, a remote attacker could execute arbitrary commands with user privileges.
(CVE-2006-7236, CVE-2008-2382).
