Description Tomas Hoger 2016-09-26 10:47:57 UTC
Quoting form the OpenSSL upstream advisory:

Missing CRL sanity check (CVE-2016-7052)

Severity: Moderate

This issue only affects OpenSSL 1.0.2i, released on 22nd September 2016.

A bug fix which included a CRL sanity check was added to OpenSSL 1.1.0
but was omitted from OpenSSL 1.0.2i. As a result any attempt to use
CRLs in OpenSSL 1.0.2i will crash with a null pointer exception.

OpenSSL 1.0.2i users should upgrade to 1.0.2j

The issue was reported to OpenSSL on 22nd September 2016 by Bruce Stephens and
Thomas Jakobi. The fix was developed by Matt Caswell of the OpenSSL development
