CVSS v3.1 |
| Citrix NetScaler Application Delivery Controller (ADC) and NetScaler Gateway 10.5 before build 67.13, 11.0 before build 71.22, 11.1 before build 56.19, and 12.0 before build 53.22 allow remote attackers to obtain sensitive information from the backend client TLS handshake by leveraging use of TLS with Client Certificates and a Diffie-Hellman Ephemeral (DHE) key exchange. |
| 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. |
| Citrix Provisioning Services before 7.12 allows attackers to execute arbitrary code by overwriting a function pointer. |
| 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 xen_biovec_phys_mergeable function in drivers/xen/biomerge.c in Xen might allow local OS guest users to corrupt block device data streams and consequently obtain sensitive memory information, cause a denial of service, or gain host OS privileges by leveraging incorrect block IO merge-ability calculation. |
| 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. |
| 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. |
| 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. |
| Xen allows local OS guest users to cause a denial of service (crash) or possibly obtain sensitive information or gain privileges via vectors involving transitive grants. |
| VMFUNC emulation in Xen 4.6.x through 4.8.x on x86 systems using AMD virtualization extensions (aka SVM) allows local HVM guest OS users to cause a denial of service (hypervisor crash) by leveraging a missing NULL pointer check. |
| Citrix Provisioning Services before 7.12 allows attackers to obtain sensitive kernel address information via unspecified vectors. |
| Use-after-free vulnerability in Citrix Provisioning Services before 7.12 allows attackers to execute arbitrary code via unspecified vectors. |
| 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. |
| XML external entity (XXE) vulnerability in Citrix XenMobile Server 9.x and 10.x before 10.5 RP3 allows attackers to obtain sensitive information via unspecified vectors. |
| 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. |
| 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 (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. |
| Citrix NetScaler Application Delivery Controller (ADC) and NetScaler Gateway 10.5 before build 67.13, 11.0 before build 71.22, 11.1 before build 56.19, and 12.0 before build 53.22 might allow remote attackers to decrypt TLS ciphertext data by leveraging a Bleichenbacher RSA padding oracle, aka a ROBOT attack. |
| 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. |
| Buffer overflow in Citrix Provisioning Services before 7.12 allows attackers to execute arbitrary code via unspecified vectors. |
