Debian Security Advisory DSA-1846-1 security@debian.org
http://www.debian.org/security/ Dann Frazier
July 28, 2009 http://www.debian.org/security/faq
- ------------------------------------------------------------------------
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.
