| Description: | OpenSSL has internal defaults for a directory tree where it can find a
configuration file as well as certificates used for verification in
TLS. This directory is most commonly referred to as OPENSSLDIR, and is
configurable with the --prefix / --openssldir configuration options.
For OpenSSL versions 1.1.0 and 1.1.1, the mingw configuration targets
assume that resulting programs and libraries are installed in a Unix-
like environment and the default prefix for program installation as
well as for OPENSSLDIR should be '/usr/local'. However, mingw programs
are Windows programs, and as such, find themselves looking at sub-
directories of 'C:/usr/local', which may be world writable, which
enables untrusted users to modify OpenSSL's default configuration,
insert CA certificates, modify (or even replace) existing engine
modules, etc. For OpenSSL 1.0.2, '/usr/local/ssl' is used as default
for OPENSSLDIR on all Unix and Windows targets, including Visual C
builds. However, some build instructions for the diverse Windows
targets on 1.0.2 encourage you to specify your own --prefix. OpenSSL
versions 1.1.1, 1.1.0 and 1.0.2 are affected by this issue. Due to the
limited scope of affected deployments this has been assessed as low
severity and therefore we are not creating new releases at this time.
Fixed in OpenSSL 1.1.1d (Affected 1.1.1-1.1.1c). Fixed in OpenSSL
1.1.0l (Affected 1.1.0-1.1.0k). Fixed in OpenSSL 1.0.2t (Affected
1.0.2-1.0.2s).
