Published: 3/3/2016Modified: 4/28/2026
Also known as:DEBIAN-CVE-2016-0702
Description
The MOD_EXP_CTIME_COPY_FROM_PREBUF function in crypto/bn/bn_exp.c in OpenSSL 1.0.1 before 1.0.1s and 1.0.2 before 1.0.2g 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, aka a "CacheBleed" attack.
Affected packages (2)
- Debian/opensslfrom 0, < 1.0.2g-1
- Debian/opensslfrom 0, < 1.0.1e-2+deb7u20
