The remote host is affected by multiple denial of service
The version of Citrix XenServer running on the remote host is affected
by multiple denial of service vulnerabilities due to multiple flaws in
the memory_exchange() function in memory.c that are triggered when
handling hypercall XENMEM_exchange errors. A local attacker within a
guest can exploit these flaws to cause a deadlock, resulting in a
denial of service condition.
