1) Information disclosure (CVE-ID: CVE-2016-0702)
The vulnerability allows a local attacker to decrypt data passed via encrypted SSL connection.The vulnerability exists in the MOD_EXP_CTIME_COPY_FROM_PREBUF() function in crypto/bn/bn_exp.c. The application does not properly consider cache-bank access times during modular exponentiation, which makes it easier for local users to discover RSA keys by running a crafted application on the same Intel Sandy Bridge CPU core as a victim and leveraging cache-bank conflicts.
The vulnerability was dubbed "CacheBleed".
