Problem summary

  • 1. Add Trust anchors for IBM cloud
    We need to be able to populate keystore with the trust anchors
    needed to deploy and operate within the IBM Cloud.
    2. Private key objects leak in HSM
    iKeyman sometimes leak private key objects in HSM. The problem
    is the public key attribute "CKA_VERIFY" (keys used for
    verifying) is required to be set to TRUE to list both the
    private key and Trusted cert entry and thus avoid private key
    leak problem. In iKeyman code, this attribute was set to default
    value "FALSE".
    3. Vulnerability reported by IBM AppScan
    IBM Appscan reports that BufferedReader.readLine() method is
    prone to Allocation of Resources Without Limits and Reliance of
    untrusted input. (i.e. exhaust heap)
    

Problem conclusion

  • 1. Add Trust anchors for IBM cloud
    Following options are introduced to add trust anchors for IBM
    cloud to the existing keystore
    -ibmcloudtrust which applies to the -create and -convert
    operations.
    -addtrust adds legacy default set of trusted CAs or those
    required for deployment within IBM Cloud.
    2. Private key objects leak in HSM
    iKeyman code is fixed to set this attribute CKA_VERIFY to TRUE.
    Also, iKeyman CLI command parameter "-crypto" is modified to
    enable the user to pick up the token library filename from
    PKCS11 configuration file specified for the IBMPKCS11Impl
    security provider in java.security file. For more information,
    please refer to the latest iKeyman user guide.
    3. Vulnerability reported by IBM AppScan
    Replace BufferedReader.readLine() method with an internal API
    that imposes limits both on the length of each line and total
    number of lines read.
    .
