ALPINE-CVE-2017-10911

The makeresponse function in drivers/block/xen-blkback/blkback.c in the Linux kernel before 4.11.8 allows guest OS users to obtain sensitive information from host OS or other guest OS kernel memory by leveraging the copying of uninitialized padding fields in Xen block-interface response structure...

blkif responses leak backend stack data

ISSUE DESCRIPTION The block interface response structure has some discontiguous fields. Certain backends populate the structure fields of an otherwise uninitialized instance of this structure on their stacks, leaking data through the internal or trailing padding field. IMPACT A malicious...

Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 3.10.5 Description: The issue allows guest OS users to cause a denial of service, resulting in data loss, by performing filesystem write operations on a read-only disk that supports either the BLKIF OP DISCARD...

kernel: guest->host denial of service from invalid xenbus transitions

The backend driver in Xen 3.x allows guest OS users to cause a denial of service via a kernel thread leak, which prevents the device and guest OS from being shut down or create a zombie domain, causes a hang in zenwatch, or prevents unspecified xm commands from working properly, related to 1...
