CVE-2019-14318

Crypto++ has a timing side-channel in ECDSA signature generation in version 8.3.0 and earlier. The underlying issue is non-constant-time scalar multiplication: ecp.cpp leaks scalar bit-length on prime-field curves and algebra.cpp leaks more on binary-field curves, enabling an attacker measuring d...

CVE-2019-14318

Crypto++ 8.3.0 and earlier contains a timing side channel in ECDSA signature generation. This allows a local or remote attacker, able to measure the duration of hundreds to thousands of signing operations, to compute the private key used. The issue occurs because scalar multiplication in ecp.cpp...

Yubico Security Keys with a Crypto Flaw

ROHNP: Key Extraction Side Channel in Multiple Crypto Libraries

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 the use of blinding during the signing process in the gcryeccecdsasign function in cipher/ecc-ecdsa.c, aka the Return Of the Hidden Number Problem or ROHNP. T...

Side-channel Attack

httpd is vulnerable to side-channel attack. An implementation flaw was discovered in multiple cryptographic libraries that allows a side-channel based attacker to recover ECDSA or DSA private keys. When these cryptographic libraries use the private key to create a signature, such as for a TLS or...

The vulnerability of the ECDSA encryption algorithm implementation in the OpenSSL library allows a perpetrator to gain unauthorized access to protected information.

The vulnerability of the ECDSA encryption algorithm implementation in the OpenSSL library is related to errors in the management of cryptographic keys. Exploiting this vulnerability could allow a malicious actor to remotely restore the encrypted private key...
