Comment 2 Huzaifa S. Sidhpurwala 2017-09-08 04:42:58 UTC
Statement:

NSS uses a local DBM database to store configuration and security (Certificates etc) information. These database files are created by NSS during startup and is used during its normal operation. These files are not read/retrieved from an external source. This flaw is related to specially-crafted NSS DBM files. So the only way to exploit this flaw is to replace the local NSS db with these files which require local user access on the machine running NSS. Therefore Red Hat Product Security does not consider this as a security flaw.
