Description

This collective June/2011 Update for Xen provides the following fixes :

  • Xen does not properly check the upper boundary of user-supplied data in the get_free_port() function when getting a new event channel port. A local user on the guest operating system can exploit this flaw to cause denial of service conditions or potentially gain elevated privileges. (CVE-2011-1166)

  • 654798: Fix race between hotplug scripts writing to xenstore and xend registering a watch for the write.

  • 684297: HVM taking too long to dump vmcore

  • 688757: Fix kernel panic on fully virtualized setup

  • 658413: Fix root drive search on SLES 10-SP3 HVM guest

  • 675363: Random lockups with kernel-xen related to graphics
