Synopsis

The remote OracleVM host is missing one or more security updates.

Description

The remote OracleVM system is missing necessary patches to address critical security updates :

- x86: check segment descriptor read result in 64-bit OUTS emulation When emulating such an operation from a 64-bit context (CS has long mode set), and the data segment is overridden to FS/GS, the result of reading the overridden segment's descriptor (read_descriptor) is not checked. If it fails, data_base is left uninitialized.
This can lead to 8 bytes of Xen's stack being leaked to the guest (implicitly, i.e. via the address given in a #PF). Coverity-ID: 1055116 This is CVE-2013-4368 / XSA-67.

Fix formatting. (CVE-2013-4368)

Solution

Update the affected xen / xen-devel / xen-tools packages.
