CVE ID: CVE-2017-9526

Description: 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.

Test IDs: 1.3.6.1.4.1.25623.1.0.703880 1.3.6.1.4.1.25623.1.1.4.2017.1608.1
