IBM Spectrum Protect Operations Center 7.1 and 8.1 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. IBM X-Force ID: 192156.
