VUL-1: CVE-2016-2178: openssl: Fix DSA, preserve BN_FLG_CONSTTIME
Last modified: 2022-02-16 21:24:17 UTC
via openssl git 1.0.1 branch commit: commit d168705e11526a4b487640c7cac5b53ee3646cbc Author: Cesar Pereida <cesar.pereida@aalto.fi> Date: Mon May 23 12:45:25 2016 +0300 Fix DSA, preserve BN_FLG_CONSTTIME Operations in the DSA signing algorithm should run in constant time in order to avoid side channel attacks. A flaw in the OpenSSL DSA implementation means that a non-constant time codepath is followed for certain operations. This has been demonstrated through a cache-timing attack to be sufficient for an attacker to recover the private DSA key.

An additional fix is commit 3681a4558c13198944e6f7f149c4be188e076e14 Author: Matt Caswell <matt@openssl.org> Date: Tue Jun 7 09:12:51 2016 +0100 More fix DSA, preserve BN_FLG_CONSTTIME The previous "fix" still left "k" exposed to constant time problems in the later BN_mod_inverse() call. Ensure both k and kq have the BN_FLG_CONSTTIME flag set at the earliest opportunity after creation.
