This disabled the tracing functionality by making functions do

Use the environment variables OPENSSL_TRACE to determine what's going
to be enabled. The value of this variables is a comma separated list
of trace and debugging names, which correspond to the trace category
macros defined in include/openssl/trace.h.
For example, setting OPENSSL_DEBUG=TRACE,SSL will enable debugging output
for the types OSSL_TRACE_CATEGORY_TRACE and OSSL_TRACE_CATEGORY_SSL.
This also slightly changes the handling of the prefix method in
apps/apps.c. This is for the better, as the prefix method pointer was
unneccessarily stored in two places.

The idea is that the application shall be able to register output
channels or callbacks to print tracing output as it sees fit.
OpenSSL internals, on the other hand, want to print thoses texts using
normal printing routines, such as BIO_printf() or BIO_dump() through
well defined BIOs.
When the application registers callbacks, the tracing functionality
sets up an internal BIO that simply forwards received text to the
appropriate application provided callback.

From a Unix point of view, some other platform families have certain
quirks. Windows command prompt doesn't expand globs into actual file
names, so we must do this. VMS has some oddity with argv pointer size
that can cause crashes if you're not careful (by copying it to a less
surprising pointer size array).
The fixups already exist and are used in the apps/ code. However, the
testutil code started using the opt routines from apps/ without
including the non-Unix fixups. This change fixes that.
For VMS' sake, libtestutil gets an app_malloc() shim, to avoid sucking
in all of apps/apps.c.

The "hw" and "hw-.*" style options are historical artifacts, sprung
from the time when ENGINE was first designed, with hardware crypto
accelerators and HSMs in mind.
Today, these options have largely lost their value, replaced by
options such as "no-{foo}eng" and "no-engine".
This completes the transition by making "hw" and "hw-.*" deprecated,
but automatically translated into more modern variants of the same.
In the process, we get rid of the last regular expression in
Configure's @disablables, a feature that was ill supported anyway.
Also, padlock now gets treated just as every other engine.

(cherry picked from commit f408e2a352)
Thanks to David Benjamin who reported this, performed the analysis and
suggested the patch. I have incorporated some of his analysis in the
comments below.
This issue can cause an out-of-bounds read. It is believed that this was
not reachable until the recent "fixed top" changes. Analysis has so far
only identified one code path that can encounter this - although it is
possible that others may be found. The one code path only impacts 1.0.2 in
certain builds. The fuzzer found a path in RSA where iqmp is too large. If
the input is all zeros, the RSA CRT logic will multiply a padded zero by
iqmp. Two mitigating factors:
- Private keys which trip this are invalid (iqmp is not reduced mod p).
Only systems which take untrusted private keys care.
- In OpenSSL 1.1.x, there is a check which rejects the oversize iqmp,
so the bug is only reproducible in 1.0.2 so far.
Fortunately, the bug appears to be relatively harmless. The consequences of
bn_cmp_word's misbehavior are:
- OpenSSL may crash if the buffers are page-aligned and the previous page is
non-existent.
- OpenSSL will incorrectly treat two BN_ULONG buffers as not equal when they
are equal.
- Side channel concerns.
The first is indeed a concern and is a DoS bug. The second is fine in this
context. bn_cmp_word and bn_cmp_part_words are used to compute abs(a0 - a1)
in Karatsuba. If a0 = a1, it does not matter whether we use a0 - a1 or
a1 - a0. The third would be worth thinking about, but it is overshadowed
by the entire Karatsuba implementation not being constant time.
Due to the difficulty of tripping this and the low impact no CVE is felt
necessary for this issue.
