CVE-2024-0914
A timing side-channel vulnerability has been discovered in the opencryptoki package while processing RSA PKCS1 v1.5 padded ciphertexts. This flaw could potentially enable unauthorized RSA ciphertext decryption or signing, even without access to the corresponding private key. Mitigation Mitigation...
gnutls: timing side-channel in the RSA-PSK authentication
A vulnerability was found that the response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from response times of ciphertexts with correct PKCS1 v1.5 padding...
openCryptoki Security Vulnerability
openCryptoki is openCryptoki open source a PKCS11 library and tool for Linux. A security vulnerability exists in openCryptoki that stems from the discovery of a timing side channel vulnerability when processing RSA PKCS1 v1.5 padded ciphertexts. This flaw could also lead to unauthorized decryptio...

Code injection
A timing side-channel issue was addressed with improvements to constant-time computation in cryptographic functions. This issue is fixed in macOS Sonoma 14.3, watchOS 10.3, tvOS 17.3, iOS 17.3 and iPadOS 17.3. An attacker may be able to decrypt legacy RSA PKCS1 v1.5 ciphertexts without having the...
CVE-2024-21484
A flaw was found in jsrsasign, which is vulnerable to an observable discrepancy via the RSA PKCS1.5 or RSAOAEP decryption process. This flaw allows an attacker to decrypt ciphertexts. Exploiting this vulnerability requires the attacker to have access to a large number of ciphertexts encrypted wit...
Spoofing
Versions of the package jsrsasign before 11.0.0 are vulnerable to Observable Discrepancy via the RSA PKCS1.5 or RSAOAEP decryption process. An attacker can decrypt ciphertexts by exploiting the Marvin security flaw. Exploiting this vulnerability requires the attacker to have access to a large...
Apple tvOS Security Breach
Apple tvOS is a smart TV operating system from Apple. A security vulnerability exists in Apple tvOS version 17.3, which allows an attacker to decrypt old RSA PKCS ciphertexts without a private key...
AZL-34739 CVE-2024-0553 affecting package gnutls for versions less than 3.8.3-1
A vulnerability was found in GnuTLS. The response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from the response times of ciphertexts with correct PKCS1 v1.5 padding. This issue may allow a remote attacker to perform a timing side-channel attack in the RSA-PSK key exchange,...
