CVE-2014-1569: High severity ibm cognos analytics vulnerability
Mozilla Network Security Services (NSS) could allow a remote attacker to bypass security restrictions, caused by the failure to ensure that the DER encoding of an ASN.1 length is properly formed by the definitelengthdecoder function. An attacker could exploit this vulnerability using a long byte sequence for an encoding to bypass restrictions and conduct data-smuggling attacks.
Other sources
The definitelengthdecoder 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 SECQuickDERDecodeItem function's improper handling of an arbitrary-length encoding of 0x00.
