| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2017-01-23 | CVE-2016-9386 | Permissions, Privileges, and Access Controls vulnerability in multiple products The x86 emulator in Xen does not properly treat x86 NULL segments as unusable when accessing memory, which might allow local HVM guest users to gain privileges via vectors involving "unexpected" base/limit values. | 4.6 |
| 2017-01-23 | CVE-2016-9385 | Improper Input Validation vulnerability in multiple products The x86 segment base write emulation functionality in Xen 4.4.x through 4.7.x allows local x86 PV guest OS administrators to cause a denial of service (host crash) by leveraging lack of canonical address checks. | 4.9 |
| 2017-01-23 | CVE-2016-9383 | Improper Input Validation vulnerability in multiple products Xen, when running on a 64-bit hypervisor, allows local x86 guest OS users to modify arbitrary memory and consequently obtain sensitive information, cause a denial of service (host crash), or execute arbitrary code on the host by leveraging broken emulation of bit test instructions. | 7.2 |
| 2017-01-23 | CVE-2016-9382 | Permissions, Privileges, and Access Controls vulnerability in multiple products Xen 4.0.x through 4.7.x mishandle x86 task switches to VM86 mode, which allows local 32-bit x86 HVM guest OS users to gain privileges or cause a denial of service (guest OS crash) by leveraging a guest operating system that uses hardware task switching and allows a new task to start in VM86 mode. | 4.6 |
| 2017-01-23 | CVE-2016-9381 | Race Condition vulnerability in multiple products Race condition in QEMU in Xen allows local x86 HVM guest OS administrators to gain privileges by changing certain data on shared rings, aka a "double fetch" vulnerability. | 6.9 |
| 2017-01-23 | CVE-2016-9380 | Improper Input Validation vulnerability in multiple products The pygrub boot loader emulator in Xen, when nul-delimited output format is requested, allows local pygrub-using guest OS administrators to read or delete arbitrary files on the host via NUL bytes in the bootloader configuration file. | 4.6 |
| 2017-01-23 | CVE-2016-9379 | Improper Input Validation vulnerability in multiple products The pygrub boot loader emulator in Xen, when S-expression output format is requested, allows local pygrub-using guest OS administrators to read or delete arbitrary files on the host via string quotes and S-expressions in the bootloader configuration file. | 4.6 |
| 2017-01-18 | CVE-2016-9680 | Information Exposure vulnerability in Citrix Provisioning Services Citrix Provisioning Services before 7.12 allows attackers to obtain sensitive information from kernel memory via unspecified vectors. | 5.0 |
| 2017-01-18 | CVE-2016-9679 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in Citrix Provisioning Services Citrix Provisioning Services before 7.12 allows attackers to execute arbitrary code by overwriting a function pointer. | 7.5 |
| 2017-01-18 | CVE-2016-9678 | Use After Free vulnerability in Citrix Provisioning Services Use-after-free vulnerability in Citrix Provisioning Services before 7.12 allows attackers to execute arbitrary code via unspecified vectors. | 7.5 |
