What is CVE-2020-4956?

IBM Spectrum Protect Operations Center versions 7.1 and 8.1 are susceptible to a denial of service due to a vulnerability in the RPC mechanism. This flaw allows a remote attacker to set an unusually large cache value that can be repeatedly dumped to a file, leading to excessive memory consumption and potentially rendering the service unavailable. This presents a significant risk for organizations relying on this product for data protection and management.
