Impact is privilege escalation, with potential information leaks/DoS as noted in sources. The issue a...

CVE-2017-10917

CVE-2017-10917 refers to a NULL pointer dereference in Xen’s event polling code, which can allow a guest user to cause a denial of service on the host. It is listed among multiple Xen regressions resolved in Debian DSA-3969 and Debian’s corresponding package fixes for stretch (Xen 4.8.x line). Af...

CVE-2017-10912

CVE-2017-10912 affects Xen hypervisor; Xen 4.8.x and older mishandles page transfers (XSA-217), enabling a privileged guest OS escalation to host OS. The issue is central to Xen’s grant/page handling and can lead to host-level privilege escalation, per Debian/GLSA coverage. Remediation in public ...

CVE-2017-10911

Summary: CVE-2017-10911 affects the Linux kernel driver path drivers/block/xen-blkback/blkback.c, related to Xen block-interface responses (XSA-216). The vulnerability arises from copying uninitialized padding fields in Xen blkback response structures, which can let a guest OS user read host (or ...

CVE-2017-10923

CVE-2017-10923 affects the Xen hypervisor (Xen 4.8.x and earlier). The root cause is a missing validation of the vCPU array index when an SGI is sent, which can allow a guest OS user to trigger a denial of service resulting in a hypervisor crash (XSA-225). The connected documents describe this as...

CVE-2017-10916

CVE-2017-10916 is an information-leak flaw in the Xen vCPU context-switch handling of Memory Protection Extensions (MPX) and Protection Key (PKU). The issue enables guest OS users to potentially bypass ASLR and related protections. Public advisories (Debian, SUSE, Fedora/OpenVAS/NASL) associate t...

CVE-2017-10915

This CVE refers to Xen shadow-paging: through Xen up to 4.8.x, incorrect reference counting in shadow paging leads to a race that can let a guest OS user gain Xen privileges (XSA-219). The Debian DLA-1132 entry notes patching and fixes for related Xen issues, but does not specify exact patched ve...

CVE-2017-10920

The grant-table feature in Xen through 4.8.x mishandles a GNTMAPdevicemap and GNTMAPhostmap mapping, when followed by only a GNTMAPhostmap unmapping, which allows guest OS users to cause a denial of service count mismanagement and memory corruption or obtain privileged host OS access, aka XSA-224...

CVE-2017-10919

CVE-2017-10919 affects the Xen hypervisor (up to 4.8.x) due to incorrect handling of virtual interrupt injection on ARM, allowing denial of service (hypervisor crash) for guest OS users. Connected documents confirm mitigations in package updates: Debian’s DSA-3969-1 fixes CVE-2017-10919 in Xen 4....

CVE-2017-10913

The grant-table feature in Xen through 4.8.x provides false mapping information in certain cases of concurrent unmap calls, which allows backend attackers to obtain sensitive information or gain privileges, aka XSA-218 bug 1...
