CVSS v3.1 |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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 |
| The rate limiting feature in NTP 4.x before 4.2.8p4 and 4.3.x before 4.3.77 allows remote attackers to have unspecified impact via a large number of crafted requests. |
| The ntpd client in NTP 4.x before 4.2.8p4 and 4.3.x before 4.3.77 allows remote attackers to cause a denial of service via a number of crafted "KOD" messages. |
| The TLS and DTLS processing functionality in Citrix NetScaler Application Delivery Controller (ADC) and NetScaler Gateway devices with firmware 9.x before 9.3 Build 68.5, 10.0 through Build 78.6, 10.1 before Build 130.13, 10.1.e before Build 130.1302.e, 10.5 before Build 55.8, and 10.5.e before Build 55.8007.e makes it easier for man-in-the-middle attackers to obtain cleartext data via a padding-oracle attack, a variant of CVE-2014-3566 (aka POODLE). |
| Xen through 4.8.x allows local x86 PV guest OS kernel administrators to cause a denial of service (host hang or crash) by modifying the instruction stream asynchronously while performing certain kernel operations. |
| The (1) ioport_read and (2) ioport_write functions in Xen, when qemu is used as a device model within Xen, might allow local x86 HVM guest OS administrators to gain qemu process privileges via vectors involving an out-of-range ioport access. |
| In certain Citrix products, information disclosure can be achieved by an authenticated VPN user when there is a configured SSL VPN endpoint. This affects Citrix ADC and Citrix Gateway 13.0-58.30 and later releases before the CTX276688 update. |
| Citrix VDI-in-a-Box 5.3.x before 5.3.6 and 5.4.x before 5.4.3 allows local users to obtain administrator credentials by reading the log. |
| Cross-site scripting (XSS) vulnerability in Citrix NetScaler Gateway (formerly Citrix Access Gateway Enterprise Edition) 9.x before 9.3.66.5 and 10.x before 10.1.123.9 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors. |
| Cross-site scripting (XSS) vulnerability in the user interface in the AAA TM vServer in Citrix NetScaler Application Delivery Controller (ADC) 9.3.x before 9.3-64.4, 10.0 before 10.0-77.5, and 10.1 before 10.1-118.7 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors. |
| Citrix NetScaler Application Delivery Controller (ADC) 9.3.x before 9.3-64.4, 10.0 before 10.0-77.5, and 10.1 before 10.1-118.7 allows remote attackers to conduct an LDAP injection attack via vectors related to SSH and Web management usernames. |
| Cross-site request forgery (CSRF) vulnerability in Citrix NetScaler Application Delivery Controller (ADC) 9.3.x before 9.3-64.4, 10.0 before 10.0-77.5, and 10.1 before 10.1-118.7 allows remote attackers to hijack the authentication of unspecified victims via unknown vectors. |
| Unspecified vulnerability in Citrix NetScaler Application Delivery Controller (ADC) 9.3.x before 9.3-64.4, 10.0 before 10.0-77.5, and 10.1 before 10.1-118.7 allows users to "breakout" of the shell via unknown vectors. |
