Security Advisory Description An issue was discovered in the jsrsasign package through 8.0.18 for Node.js. It allows a malleability in ECDSA signatures by not checking overflows in the length of a sequence and '0' characters appended or prepended to an integer. The modified signatures are verifie...

ECDSA signature validation vulnerability by accepting wrong ASN.1 encoding in jsrsasign

Impact Jsrsasign supports ECDSA signature validation which signature value is represented by ASN.1 DER encoding. This vulnerablity may accept a wrong ASN.1 DER encoded ECDSA signature such as: - wrong multi-byte ASN.1 length of TLV ex. 0x820045 even though 0x45 is correct - prepending zeros with...

An issue was discovered in the jsrsasign package through 8.0.18 for Node.js. It allows a malleability in ECDSA signatures by not checking overflows in the length of a sequence and '0' characters appended or prepended to an integer.

CVE-2020-14966

The CVE-2020-14966 issue affects the jsrsasign package up to version 8.0.18 in Node.js. Root cause: malleability in ECDSA signatures from insufficient checks of ASN.1/DER encoding, specifically overflow in sequence length and prepended/appended zeroes to integers, allowing altered signatures to v...
