NVIDIA GPU Display Driver for Windows and Linux contains a vulnerability in the kernel mode layer, where a local user with basic capabilities can cause a null-pointer dereference, which may lead to denial of service.

xen: x86 null segments not always treated as unusable (XSA-191)

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.

An issue was discovered in Linux Foundation xapi in Citrix XenServer through 7.0. An authenticated read-only administrator can cancel tasks of other administrators.

Citrix NetScaler ADC and NetScaler Gateway 10.5 before Build 65.11, 11.0 before Build 69.12/69.123, and 11.1 before Build 51.21 randomly generates GCM nonces, which makes it marginally easier for remote attackers to obtain the GCM authentication key and spoof data by leveraging a reused nonce in a session and a "forbidden attack," a similar issue to CVE-2016-0270.

An issue was discovered in Linux Foundation xapi in Citrix XenServer through 7.0. An authenticated read-only administrator can corrupt the host database.

A vulnerability has been identified in the management interface of Citrix NetScaler Application Delivery Controller (ADC) and NetScaler Gateway 10.1 before build 135.18, 10.5 before build 66.9, 10.5e before build 60.7010.e, 11.0 before build 70.16, 11.1 before build 55.13, and 12.0 before build 53.13 (except for build 41.24) that, if exploited, could allow an attacker with access to the NetScaler management interface to gain administrative access to the appliance.

Citrix XenMobile Server before 10.5.0.24 allows man-in-the-middle attackers to trigger HTTP 302 redirections via vectors involving the HTTP Host header and a cached page. NOTE: the vendor reports "our internal analysis of this issue concluded that this was not a valid vulnerability" because an exploitation scenario would involve a man-in-the-middle attack against a TLS session
