Quoted from the link above:
OpenSSL Security Advisory [26 Sep 2016]
========================================
This security update addresses issues that were caused by patches
included in our previous security update, released on 22nd September
2016. Given the Critical severity of one of these flaws we have
chosen to release this advisory immediately to prevent upgrades to the
affected version, rather than delaying in order to provide our usual
public pre-notification.
Fix Use After Free for large message sizes (CVE-2016-6309)
==========================================================
Severity: Critical
This issue only affects OpenSSL 1.1.0a, released on 22nd September 2016.
The patch applied to address CVE-2016-6307 resulted in an issue where if a
message larger than approx 16k is received then the underlying buffer to store
the incoming message is reallocated and moved. Unfortunately a dangling pointer
to the old location is left which results in an attempt to write to the
previously freed location. This is likely to result in a crash, however it
could potentially lead to execution of arbitrary code.
OpenSSL 1.1.0 users should upgrade to 1.1.0b
This issue was reported to OpenSSL on 23rd September 2016 by Robert
Święcki (Google Security Team), and was found using honggfuzz. The fix
was developed by Matt Caswell of the OpenSSL development team.
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
team.

Ludo, you mentioned you were using this graft as a test case for
improvements to `guix lint`. Let us know if you are done with it so it
can be ungrafted on the core-updates branch.

Go ahead, I’m done!
What I meant by “test case” is just commit
8389e6f06efde73ebb849a82e0967eb6afec8c39: now the replacement is called
“1.0.2j”, not “1.0.2h”.
