30 Oct 2017 — An issue was discovered in Xen through 4.9.x. Grant copying code made an implication that any grant pin would be accompanied by a suitable page reference. Other portions of code, however, did not match up with that assumption. When such a grant copy operation is being done on a grant of a dying domain, the assumption turns out wrong. A malicious guest administrator can cause hypervisor memory corruption, most likely resulting in host crash and a Denial of Service. • http://www.openwall.com/lists/oss-security/2017/10/24/3 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
