computer vulnerability alert CVE-2016-9932

Xen: information disclosure via CMPXCHG8B

Synthesis of the vulnerability

A local attacker, inside a guest system, can use an instruction CMPXCHG8B, in order to fetch some bytes of Xen' stack, on the host system.
Impacted products: XenServer, Debian, Fedora, openSUSE, openSUSE Leap, SUSE Linux Enterprise Desktop, SLES, Xen.
Severity: 1/4.
Consequences: data reading.
Provenance: user shell.
Creation date: 14/12/2016.
Identifiers: CERTFR-2016-AVI-418, CERTFR-2016-AVI-428, CTX219378, CVE-2016-9932, DLA-964-1, DSA-3847-1, FEDORA-2016-1b868c23a9, FEDORA-2016-bcbae0781f, openSUSE-SU-2017:0005-1, openSUSE-SU-2017:0007-1, openSUSE-SU-2017:0008-1, SUSE-SU-2016:3207-1, SUSE-SU-2016:3208-1, SUSE-SU-2016:3221-1, SUSE-SU-2016:3241-1, SUSE-SU-2017:0718-1, VIGILANCE-VUL-21386, XSA-200.

Description of the vulnerability

The Xen product can emulate x86 instructions.

Some instructions may be modified with an operand size prefix that states the length of the memory access. Thus prefix should not be taken into account for the instruction CMPXCHG8B. However, some parts of the hypervisor do use it.

A local attacker, inside a guest system, can therefore use an instruction CMPXCHG8B, in order to fetch some bytes of Xen' stack, on the host system.
