Descriptions

The InvertibleRWFunction::CalculateInverse function in rw.cpp in libcrypt++ 5.6.2 does not properly blind private key operations for the Rabin-Williams digital signature algorithm, which allows remote attackers to obtain private keys via a timing attack.

La función InvertibleRWFunction::CalculateInverse en rw.cpp en libcrypt++ 5.6.2 no ciega correctamente las operaciones de claves privadas para el algoritmo de la firma digital Rabin-Williams, lo que permite a atacantes remotos obtener claves privadas a través de un ataque de tiempos.

Evgeny Sidorov discovered that libcrypto++, a general purpose C++ cryptographic library, did not properly implement blinding to mask private key operations for the Rabin-Williams digital signature algorithm. This could allow remote attackers to mount a timing attack and retrieve the user's private key.
