Multiple flaws were found in the processing of malformed web content. A web page containing malicious content could cause Firefox to crash or, potentially, execute arbitrary code with the privileges of the user running Firefox (CVE-2017-5398, CVE-2017-5400, CVE-2017-5401, CVE-2017-5402, CVE-2017-5404, CVE-2017-5407, CVE-2017-5408, CVE-2017-5410, CVE-2017-5405).
Also, the nss package has been updated to version 3.28.3, in which the Next Protocol Negotiation (NPN) extension has been replaced by the Application-Layer Protocol Negotiation (ALPN) extension and which now supports the Finite Field Diffie-Hellman Ephemeral Parameters (FFDHE) negotiation.
Due to the nss update, the sqlite3 package has been updated to version 3.10.2.
Additionally, an error in the nss package has been corrected, where it was failing to build against the system rootcerts package and instead was using a bundled version, which could have caused the rootcerts that NSS used to be outdated at times (mga#20053). The nss package has now been built against the latest rootcerts, which have also been updated.
