**Name of the Vulnerable Software and Affected Versions** VEEAM One Agent version 9.5.4.4587 **Description** This issue allows remote attackers to execute arbitrary code on affected installations. Authentication is not required to exploit this issue. The flaw exists within the `PerformHandshake` method and results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this issue to execute code in the context of the service account. **Recommendations** For VEEAM One Agent version 9.5.4.4587, as a temporary workaround, consider restricting access to the `PerformHandshake` method until a patch is available. At the moment, there is no information about a newer version that contains a fix for this issue.

The flaw exists within the `HandshakeResult` method and results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this issue to execute code in the context of the service account. **Recommendations** For VEEAM One Agent version 9.5.4.4587, consider disabling the `HandshakeResult` method as a temporary workaround until a patch is available. Restrict access to the service account to minimize the risk of exploitation. Avoid using untrusted data in the deserialization process until the issue is resolved. 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** Apple AirPort Express versions 6.x before Firmware Update 6.3 Apple AirPort Extreme versions 5.x before Firmware Update 5.7 **Description** The issue allows remote attackers to cause a denial of service, resulting in an unresponsive interface, by sending malformed packets to the network interface. **Recommendations** For Apple AirPort Express versions 6.x, apply Firmware Update 6.3 to resolve the issue. For Apple AirPort Extreme versions 5.x, apply Firmware Update 5.7 to resolve the issue.
