**Name of the Vulnerable Software and Affected Versions** Parallels Desktop version 17.1.1 **Description** This issue allows local attackers to escalate privileges on affected installations. An attacker must first obtain the ability to execute high-privileged code on the target guest system in order to exploit this issue. The specific flaw exists within the ACPI virtual device. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this issue to escalate privileges and execute arbitrary code in the context of the hypervisor. **Recommendations** For Parallels Desktop version 17.1.1, at the moment, there is no information about a newer version that contains a fix for this issue.

**Name of the Vulnerable Software and Affected Versions** Parallels Desktop version 16.5.1 **Description** This issue allows local attackers to escalate privileges on affected installations. An attacker must first obtain the ability to execute high-privileged code on the target guest system in order to exploit this issue. The specific flaw exists within the HDAudio virtual device. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length buffer. An attacker can leverage this issue to escalate privileges and execute arbitrary code in the context of the hypervisor. **Recommendations** For Parallels Desktop version 16.5.1, at the moment, there is no information about a newer version that contains a fix for this issue.

Name of the Vulnerable Software and Affected Versions: Parallels Desktop version 16.1.3 Description: This issue allows local attackers to escalate privileges on affected installations. An attacker must first obtain the ability to execute high-privileged code on the target guest system in order to exploit this issue. The specific flaw exists within the `virtio-gpu` virtual device. The issue results from the lack of proper validation of user-supplied data, which can result in a memory corruption condition. An attacker can leverage this issue to escalate privileges and execute arbitrary code in the context of the hypervisor. Recommendations: For Parallels Desktop version 16.1.3, at the moment, there is no information about a newer version that contains a fix for this issue.

Name of the Vulnerable Software and Affected Versions: Mitsubishi Electric MC Works64 version 4.02C (10.95.208.31) and earlier Mitsubishi Electric MC Works32 version 3.00A (9.50.255.02) ICONICS GenBroker64, Platform Services, Workbench, FrameWorX Server version 10.96 and prior ICONICS GenBroker32 version 9.5 and prior Description: A specially crafted communication packet sent to the affected systems could cause a denial-of-service condition due to improper deserialization. The issue is related to deficiencies in the deserialization mechanism, which can be exploited by a remote attacker to cause a denial-of-service condition. Recommendations: For Mitsubishi Electric MC Works64 version 4.02C (10.95.208.31) and earlier, update to a version that fixes the deserialization issue. For Mitsubishi Electric MC Works32 version 3.00A (9.50.255.02), update to a version that fixes the deserialization issue. For ICONICS GenBroker64, Platform Services, Workbench, FrameWorX Server version 10.96 and prior, update to a version that fixes the deserialization issue. For ICONICS GenBroker32 version 9.5 and prior, update to a version that fixes the deserialization issue. As a temporary workaround, consider restricting access to the deserialization mechanism until a patch is available.

Name of the Vulnerable Software and Affected Versions: Mitsubishi Electric MC Works64 version 4.02C (10.95.208.31) and earlier Mitsubishi Electric MC Works32 version 3.00A (9.50.255.02) ICONICS GenBroker64, Platform Services, Workbench, FrameWorX Server version 10.96 and prior ICONICS GenBroker32 version 9.5 and prior Description: A deserialization vulnerability exists, allowing remote code execution and a denial-of-service condition due to a specially crafted communication packet sent to the affected devices. This issue is related to the restoration of an untrusted data structure in memory, which can be exploited by a remote attacker to execute arbitrary code or cause a denial-of-service. Recommendations: For Mitsubishi Electric MC Works64 version 4.02C (10.95.208.31) and earlier, update to a version later than 4.02C (10.95.208.31) to resolve the issue. For Mitsubishi Electric MC Works32 version 3.00A (9.50.255.02), update to a version later than 3.00A (9.50.255.02) to resolve the issue. For ICONICS GenBroker64, Platform Services, Workbench, FrameWorX Server version 10.96 and prior, update to a version later than 10.96 to resolve the issue. For ICONICS GenBroker32 version 9.5 and prior, update to a version later than 9.5 to resolve the issue. As a temporary workaround, consider restricting access to the deserialization functionality until a patch is available.
