Memory corruption

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-2020-14968

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...

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...

CVE-2020-12402

A flaw was found in NSS, where it is vulnerable to RSA key generation cache timing side-channel attacks. An attacker with sufficient access to mount cache timing attacks during the RSA key generation process could recover the private key. The highest threat to this flaw is to confidentiality...

EulerOS 2.0 SP2 : nss-softokn (EulerOS-SA-2020-1651)

According to the versions of the nss-softokn packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - Libgcrypt before 1.7.10 and 1.8.x before 1.8.3 allows a memory-cache side-channel attack on ECDSA signatures that can be mitigated through...

Nintendo: [3DS][SSL] Improper certificate validation allows an attacker to perform MitM attacks

Affected Systems - Platform: New Nintendo 3DS - Region: ALL - System version: = 11.13 Description The SSL system module does not properly validate the x509 certificates when establishing an SSL/TLS connection. Actually, the SSL system module does not check the signatures when validating a...

Tycoon Ransomware Banks on Unusual Image File Tactic

A new ransomware strain called Tycoon is seeking to wheel and deal its way into the Windows and Linux worlds, using a little-known Java image format as part of its kill chain. The ransomware is housed in a trojanized version of the Java Runtime Environment JRE, according to researchers at...
