DEBIAN-CVE-2020-11739

An issue was discovered in Xen through 4.13.x, allowing guest OS users to cause a denial of service or possibly gain privileges because of missing memory barriers in read-write unlock paths. The read-write unlock paths don't contain a memory barrier. On Arm, this means a processor is allowed to...

DEBIAN-CVE-2020-11741

An issue was discovered in xenoprof in Xen through 4.13.x, allowing guest OS users with active profiling to obtain sensitive information about other guests, cause a denial of service, or possibly gain privileges. For guests for which "active" profiling was enabled by the administrator, the xenopr...

CVE-2020-11742

An issue was discovered in Xen through 4.13.x, allowing guest OS users to cause a denial of service because of bad continuation handling in GNTTABOPcopy. Grant table operations are expected to return 0 for success, and a negative number for errors. The fix for CVE-2017-12135 introduced a path...

Citrix Hypervisor Multiple Security Updates

Description of Problem Several issues have been identified within Citrix Hypervisor, which could, if exploited, allow: privileged code in a PV guest VM to read a single uninitialized 4kB page of memory that may contain data left by a previous VM privileged code in a guest VM to cause the host to...

The vulnerability of Xen hypervisors arises from the simultaneous execution using a shared resource with incorrect synchronization. This allows attackers to gain access to confidential data, compromise its integrity, and cause service failures.

The vulnerability of Xen hypervisors is related to an error in the restart operations for volume change operations. Exploiting this vulnerability can allow a remote attacker to gain access to confidential data, compromise its integrity, and cause service failures...

The vulnerability of Xen hypervisors relates to the improper assignment of permissions for critical resources. This allows attackers to gain access to confidential data, compromise its integrity, and cause service failures.

The vulnerability of Xen hypervisors is related to the occurrence of exceptions that are handled without modifying the processor’s level. Some interrupts are inevitably included when an exception is generated. Exploiting this vulnerability can allow a remote attacker to access confidential data,...
