-
The product generates an error message that includes sensitive information about its environment, users, or associated data.Assigned by: prodsec@nozominetworks.com (Secondary)
-
The elevated privilege level required to perform operations such as chroot() should be dropped immediately after the operation is performed.Assigned by: prodsec@nozominetworks.com (Secondary)
-
The authentication algorithm is sound, but the implemented mechanism can be bypassed as the result of a separate weakness that is primary to the authentication error.Assigned by: prodsec@nozominetworks.com (Secondary)
-
The product stores or transmits sensitive data using an encryption scheme that is theoretically sound, but is not strong enough for the level of protection required.Assigned by: nvd@nist.gov (Primary)
