Описание
In Libgcrypt before 1.7.7, an attacker who learns the EdDSA session key (from side-channel observation during the signing process) can easily recover the long-term secret key. 1.7.7 makes a cipher/ecc-eddsa.c change to store this session key in secure memory, to ensure that constant-time point operations are used in the MPI library.
Отчет
This issue did not affect the versions of libgcrypt as shipped with Red Hat Enterprise Linux 5, 6 and 7 as they did not include support for EdDSA cipher.
