    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.
