CVE-2020-14967

An issue was discovered in the jsrsasign package before 8.0.18 for Node.js. Its RSA PKCS1 v1.5 decryption implementation does not detect ciphertext modification by prepending '\0' bytes to ciphertexts it decrypts modified ciphertexts without error. An attacker might prepend these bytes with the...

CVE-2020-14966

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 verified as valid. This could have a...

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...

CVE-2020-14968

The CVE-2020-14968 issue affects the jsrsasign package for Node.js prior to 8.0.17. Its RSASSA-PSS verification accepts signatures prepended with zero bytes, enabling an attacker to create multiple valid signatures where only one should exist and potentially trigger memory corruption. The confirm...

CVE-2020-14967

CVE-2020-14967 affects the jsrsasign package for Node.js prior to version 8.0.18. The RSA PKCS1 v1.5 decryption path does not detect ciphertext modifications when zeros are prepended to ciphertexts, allowing modified ciphertexts to be decrypted without error and potentially triggering memory corr...
