Package        : xen
CVE ID         : CVE-2015-2044 CVE-2015-2045 CVE-2015-2151

Multiple security issues have been found in the Xen virtualisation
solution:

CVE-2015-2044

    Information leak via x86 system device emulation.

CVE-2015-2045

    Information leak in the HYPERVISOR_xen_version() hypercall.

CVE-2015-2151

    Missing input sanitising in the x86 emulator could result in
    information disclosure, denial of service or potentially
    privilege escalation.

In addition the Xen developers reported an unfixable limitation in the
handling of non-standard PCI devices. Please refer to
http://xenbits.xen.org/xsa/advisory-124.html for further information.

For the stable distribution (wheezy), these problems have been fixed in
version 4.1.4-3+deb7u5.

For the unstable distribution (sid), these problems will be fixed soon.

We recommend that you upgrade your xen packages.
