- CVEs with nessus.description==The remote host is running a version of Citrix XenServer that is affected by multiple vulnerabilities :
- A local privilege escalation vulnerability exists due to improperly restricted access to 'PHYSDEVOP_{prepare,release}_msix' operations by unprivileged guests. An attacker with access to a guest operating system can exploit this issue to gain elevated privileges on affected computers. (CVE-2014-1666)
- A local privilege escalation vulnerability exists due to missing privilege level checks in x86 emulation of far branches. This flaw exists in the CALL, JMP, and RETF instructions in the Intel assembly syntax, and the LCALL, LJMP, and LRET instructions in the AT&T syntax.
An attacker with access to a guest operating system can exploit this issue to gain elevated privileges on affected computers. (CVE-2014-8595)
- A denial of service vulnerability exists due to a failure to restrict access to the hypercall argument translation feature. An attacker with access to a guest operating system can crash the host with excessive checks on the final register state for 32-bit guests running on a 64-bit hypervisor. (CVE-2014-8866)
- A denial of service vulnerability exists due to insufficient bounding of 'REP MOVS' to MMIO emulated inside of the hypervisor. This flaw affects the 'hvm_mmio_intercept()' function in 'intercept.c'. An attacker with access to a guest operating system can exploit this issue to crash the host.
