Upstream information

CVE-2013-4368 at MITRE

Description

The outs instruction emulation in Xen 3.1.x, 4.2.x, 4.3.x, and earlier, when using FS: or GS: segment override, uses an uninitialized variable as a segment base, which allows local 64-bit PV guests to obtain sensitive information (hypervisor stack content) via unspecified vectors related to stale data in a segment register.

Note from the SUSE Security Team on the xen package

This issue likely only affects the XEN hypervisor itself, unless otherwise stated. The userland utilities in -tools and libraries in -libs are shipped together with the xen hypervisor as they are built from one source and do not contain hypervisor specific fixes.
