Package : kvm Vulnerability : denial of service Problem type : local Debian-specific: no CVE Id(s) : CVE-2009-2287
Matt T. Yourst discovered an issue in the kvm subsystem. Local users with permission to manipulate /dev/kvm can cause a denial of service (hang) by providing an invalid cr3 value to the KVM_SET_SREGS call.
For the stable distribution (lenny), these problems have been fixed in version 72+dfsg-5~lenny2.
For the unstable distribution (sid), these problems will be fixed soon.
We recommend that you upgrade your kvm packages, and rebuild any kernel modules you have built from a kvm-source package version.
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.
Debian GNU/Linux 5.0 alias lenny - --------------------------------
Stable updates are available for amd64 and i386.
