| The sec_asn1d_parse_leaf function in Mozilla Network Security Services
(NSS) before 3.19.2.1 and 3.20.x before 3.20.1, as used in Firefox
before 42.0 and Firefox ESR 38.x before 38.4 and other products,
improperly restricts access to an unspecified data structure, which
allows remote attackers to cause a denial of service (application
crash) or possibly execute arbitrary code via crafted OCTET STRING
data, related to a "use-after-poison" issue.
