CVE-2014-1569
HighSummary
The definite_length_decoder function in lib/util/quickder.c in Mozilla Network Security Services (NSS) before version 3.16.2.4 and 3.17.x before version 3.17.3 does not ensure that the DER encoding of an ASN.1 length is properly formed. This allows remote attackers to conduct data-smuggling attacks by using a long byte sequence for an encoding.
Risk Assessment
Attackers can exploit this vulnerability to manipulate data, potentially leading to unauthorized access or data loss in systems using the vulnerable version of NSS.
Recommendation
It is recommended to update Mozilla Network Security Services to version 3.16.2.4 or 3.17.3 and to monitor systems for unauthorized activities.
Other vulnerabilities in Mozilla Network Security Services (NSS)
See all- CVE-2017-5461Critical
Mozilla Network Security Services (NSS) versions before 3.21.4, 3.22.x through 3.28.x before 3.28.4, 3.29.x before 3.29.5, and 3.30.x before 3.30.1 are vulnerable to remote attacks that can cause denial of service (out-of-bounds write) or possibly have unspecified other impact by leveraging incorrect base64 operations.
- CVE-2015-7182Critical
A heap-based buffer overflow in the ASN.1 decoder in Mozilla Network Security Services (NSS) before 3.19.2.1 and 3.20.x before 3.20.1 can lead to application crashes or potentially allow remote attackers to execute arbitrary code via crafted OCTET STRING data.
Original NVD description (English source)
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.
