here are multiple out of bounds (OOB) read vulnerabilities in the implementation of the Common Open Policy Service (COPS) protocol of some Huawei products. The specific decoding function may occur out-of-bounds read when processes an incoming data packet. Successful exploit of these vulnerabilities may disrupt service on the affected device. (Vulnerability ID: HWPSIRT-2018-12275,HWPSIRT-2018-12276,HWPSIRT-2018-12277,HWPSIRT-2018-12278,HWPSIRT-2018-12279,HWPSIRT-2018-12280 and HWPSIRT-2018-12289) The seven vulnerabilities have been assigned seven Common Vulnerabilities and Exposures (CVE) IDs: CVE-2020-1818, CVE-2020-1819, CVE-2020-1820, CVE-2020-1821, CVE-2020-1822, CVE-2020-1823 and CVE-2020-1824.
