A heap-based buffer overflow flaw was found in the way NSS parsed certain
ASN.1 structures. An attacker could use this flaw to create a specially
crafted certificate which, when parsed by NSS, could cause it to crash, or
execute arbitrary code, using the permissions of the user running an
application compiled against the NSS library (CVE-2016-1950).

This issue was supposed to have been fixed in MGASA-2016-0105, but Mozilla
did not include the fix until the following nss releases.");
