CVEID:CVE-2020-4956
**DESCRIPTION:**IBM Spectrum Protect Operations Center is vulnerable to a denial of service, caused by a RPC that allows certain cache values to be set and dumped to a file. By setting a grossly large cache value and dumping that cached value to a file multiple times, a remote attacker could exploit this vulnerability to cause the consumption of all memory resources.
CVSS Base score: 4.8
