The WebSphere security bulletin above provides a link to the required iFix to remediate the vulnerability. However, the iFix requires either eWAS 7.0.0.31 or higher installed.
TIP does not support upgrading WebSphere fixpack independently. TIP fixpack 2.2.0.15 or 2.2.0.17 or 2.2.0.19 must be applied which will upgrade eWAS to 7.0.0.31 and above. Once one of these TIP fixpacks has been applied, the WebSphere iFix can be applied as described in the WebSphere bulletin.
