Comment 1 Eric Blake 2011-06-28 13:58:36 UTC
Fixed by this upstream patch: commit 774b21c163845170c9ffa873f5720d318812eaf6 Author: Eric Blake <email@example.com> Date: Fri Jun 24 12:16:05 2011 -0600 remote: protect against integer overflow Integer overflow and remote code are never a nice mix. This has existed since commit 56cd414. * src/libvirt.c (virDomainGetVcpus): Reject overflow up front. * src/remote/remote_driver.c (remoteDomainGetVcpus): Avoid overflow on sending rpc. * daemon/remote.c (remoteDispatchDomainGetVcpus): Avoid overflow on receiving rpc. F14 and F15 can instead use this backport, to avoid having to update gnulib: http://post-office.corp.redhat.com/archives/rhvirt-patches/2011-June/msg00624.html Rawhide will pick up the fix by rebasing to 0.9.3.
