Description:
 The KVM implementation in the Linux kernel before 2.6.36 does not properly
 reload the FS and GS segment registers, which allows host OS users to cause
 a denial of service (host OS crash) via a KVM_RUN ioctl call in conjunction
 with a modified Local Descriptor Table (LDT).
Ubuntu-Description:
 It was discovered that KVM did not correctly initialize certain CPU
 registers. A local attacker could exploit this to crash the system, leading
 to a denial of service.
Notes:
 smb> There is no KVM in Dapper, so that cannot be affected. Maverick needed
 smb> some adaption as a previous stable patch moved code around. Lucid had
 smb> it already. Karmic mostly cherry-pick. Hardy needed more twisting.
