Descriptions

The OpenSSL DSA signature algorithm has been shown to be vulnerable to a timing side channel attack. An attacker could use variations in the signing algorithm to recover the private key. Fixed in OpenSSL 1.1.1a (Affected 1.1.1). Fixed in OpenSSL 1.1.0j (Affected 1.1.0-1.1.0i). Fixed in OpenSSL 1.0.2q (Affected 1.0.2-1.0.2p).

Se ha demostrado que el algoritmo de firmas DSA en OpenSSL es vulnerable a un ataque de sincronización de canal lateral. Un atacante podría emplear variaciones en el algoritmo de firma para recuperar la clave privada. Se ha solucionado en OpenSSL 1.1.1a (afecta a 1.1.1). Se ha solucionado en OpenSSL 1.1.0j (afecta a 1.1.0-1.1.0i). Se ha solucionado en OpenSSL 1.0.2q (afecta a 1.0.2-1.0.2p).
