- CVEs with nessus.description==According to its self-reported version number, the Xen hypervisor installed on the remote host is missing a security update. It is, therefore, affected by a denial of service vulnerability due to a flaw in the x86 instruction emulator whenever a guest asynchronously modifies its instruction stream to effect the clearing of EFLAGS.IF.
An attacker who has guest kernel administrator privileges can exploit this issue to cause the host to hang or crash.
Please note the following items :
- Only x86 PV guests can exploit the vulnerability.
- Neither ARM guests nor x86 HVM guests can exploit the vulnerability.
Note that Nessus has not tested for this vulnerability but has instead relied only on the changeset versions based on the xen.git change log.
Nessus did not check guest hardware configurations or if patches were applied manually to the source code before a recompile and reinstall.
