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-2020-14967

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...

CVE-2020-13757

A flaw was found in the python-rsa package, where it does not explicitly check the ciphertext length against the key size and ignores the leading 0 bytes during the decryption of the ciphertext. This flaw allows an attacker to perform a ciphertext attack, leading to a denial of service. The highe...

cryptacular: excessive memory allocation during a decode operation

CiphertextHeader.java in Cryptacular 1.2.3, as used in Apereo CAS and other products, allows attackers to trigger excessive memory allocation during a decode operation, because the nonce array length associated with "new byte" may depend on untrusted input within the header of encoded data...

Information Disclosure

rsa is vulnerable to information disclosure. The vulnerability exists as rsa ignores prepended \0 bytes during the decryption of a ciphertext in PKCS1v15, where it is supposed to have failed, allowing the interference that this library is used for cryptography...

CVE-2020-13757

Python-RSA before 4.1 ignores leading '\0' bytes during decryption of ciphertext. This could conceivably have a security-relevant impact, e.g., by helping an attacker to infer that an application uses Python-RSA, or if the length of accepted ciphertext affects application behavior such as by...

Memory corruption

Python-RSA before 4.1 ignores leading '\0' bytes during decryption of ciphertext. This could conceivably have a security-relevant impact, e.g., by helping an attacker to infer that an application uses Python-RSA, or if the length of accepted ciphertext affects application behavior such as by...

CVE-2020-13757

CVE-2020-13757 affects the Python-RSA package. Affected: Python-RSA before 4.1. Root cause: decryption ignores leading '\0' bytes in ciphertext. Impact stated in sources: potential DoS risk and information leakage indicators (e.g., attacker could infer usage, or ciphertext length could affect beh...

PT-2020-13658 · Python +5 · Python-Rsa +5

Name of the Vulnerable Software and Affected Versions: Python-RSA versions prior to 4.1 Description: The issue concerns the decryption of ciphertext, where leading '0' bytes are ignored. This could potentially have security implications, such as helping an attacker infer that an application uses...

CVE-2018-12404

A cached side channel attack during handshakes using RSA encryption could allow for the decryption of encrypted content. This is a variant of the Adaptive Chosen Ciphertext attack AKA Bleichenbacher attack and affects all NSS versions prior to NSS 3.41...
