CVE-2017-9526

CVE-2017-9526 affects Libgcrypt prior to 1.7.7, where an attacker who observes the EdDSA session key during signing can recover the long-term secret key. Version 1.7.7 changes libgcrypt/ ecc-eddsa.c to store the session key in secure memory and ensures constant-time point operations in the MPI li...

CVE-2017-9526

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...

Open-Xchange: Dovecot authentication is vulnerable to timing attacks.

Dear Dovecot bug bounty team, Dovecot is vulnerable to timing attacks, because the verifycredentials function in CRAM-MD5 performs a byte-by-byte comparison, which terminates early when two characters do not match. Summary --- Timing attacks are a type of side channel attack where one can discove...
