Xen CMPXCHG8B Emulation Information Disclosure (XSA-200)
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 an information disclosure vulnerability due to a flaw in the x86 instruction CMPXCHG8B when handling prefixes. This is triggered because legac...
Xen Intel VMX hvmemul_vmfunc() NULL Pointer Dereference DoS (XSA-203)
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 NULL pointer dereference flaw due to a failure to utilize necessary NULL checks before doing indirect function calls through the hvmemulvmfu...

x86: Mishandling of SYSCALL singlestep during emulation
ISSUE DESCRIPTION The typical behaviour of singlestepping exceptions is determined at the start of the instruction, with a DB trap being raised at the end of the instruction. SYSCALL and SYSRET, although we don't implement it behave differently because the typical behaviour allows userspace to...
