Out of Bounds Read Vulnerabilities in Huawei Products

CVE-2020-1821

Summary

Multiple out of bounds read vulnerabilities exist in the implementation of the Common Open Policy Service (COPS) protocol in certain Huawei devices. These vulnerabilities arise during the decoding of incoming data packets, which can result in an attacker reading memory that should not be accessible. Exploiting these vulnerabilities successfully can lead to significant service disruption on affected devices, impacting overall network reliability. It is crucial for users and administrators of Huawei devices to apply the necessary security patches to mitigate the risks associated with these vulnerabilities.
