Package : kvm
Vulnerability : several vulnerabilities
Problem type : local (remote)
Debian-specific: no
Debian bugs : 509997 548975
CVE Ids : CVE-2008-5714 CVE-2009-3290


Several vulnerabilities have been discovered in kvm, a full virtualization system.
The Common Vulnerabilities and Exposures project identifies the
following problems:

CVE-2008-5714

Chris Webb discovered an off-by-one bug limiting KVM's VNC passwords to 7
characters. This flaw might make it easier for remote attackers to guess the VNC
password, which is limited to seven characters where eight was intended.

CVE-2009-3290

It was discovered that the kvm_emulate_hypercall function in KVM does not
prevent access to MMU hypercalls from ring 0, which allows local guest OS users
to cause a denial of service (guest kernel crash) and read or write guest kernel
memory.


For the stable distribution (lenny), these problems have been fixed in version
72+dfsg-5~lenny3.

The oldstable distribution (etch) does not contain kvm.

For the testing distribution (squeeze) these problems will be fixed soon.

For the unstable distribution (sid) these problems have been fixed in version
85+dfsg-4.1


We recommend that you upgrade your kvm packages.

Upgrade instructions
- --------------------

wget url
will fetch the file for you
dpkg -i file.deb
will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
will update the internal database
apt-get upgrade
will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
