    Package : xen
    CVE ID : CVE-2015-7835

    It was discovered that the code to validate level 2 page table entries
    is bypassed when certain conditions are satisfied. A malicious PV guest administrator can take advantage of this flaw to gain privileges via a
    crafted superpage mapping.

    For the oldstable distribution (wheezy), this problem has been fixed
    in version 4.1.4-3+deb7u9.

    For the stable distribution (jessie), this problem has been fixed in
    version 4.4.1-9+deb8u2.

    We recommend that you upgrade your xen packages.
