Our Security team has scanned our environment and found below vulnerability in one of our DD;
DD2500 > CVE-1999-0519 & CVE-1999-0562
I need to know how can this DD be remediated.
You can search KB and you will find:
https://support.emc.com/kb/466389 (in essence DD is not vulnerable to 1999-0519)
For second one CVE I could not find reference to DD, but it also looks old so I doubt it is present or anyhow applicable in current code.
