NVD Description

Note: Versions mentioned in the description apply only to the upstream nss-devel package and not the nss-devel package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

The definite_length_decoder function in lib/util/quickder.c in Mozilla Network Security Services (NSS) before 3.16.2.4 and 3.17.x before 3.17.3 does not ensure that the DER encoding of an ASN.1 length is properly formed, which allows remote attackers to conduct data-smuggling attacks by using a long byte sequence for an encoding, as demonstrated by the SEC_QuickDERDecodeItem function's improper handling of an arbitrary-length encoding of 0x00.
