Description msiddiqu 2019-07-30 15:17:18 UTC
When the database server or libpq client library initializes SSL, libeay32.dll
attempts to read configuration from a hard-coded directory.  Typically, the
directory does not exist, but any local user could create it and inject
configuration.  This configuration can direct OpenSSL to load and execute
arbitrary code as the user running a PostgreSQL server or client.  Most
PostgreSQL client tools and libraries use libpq, and one can encounter this
vulnerability by using any of them.  This vulnerability is much like
CVE-2019-5443, but it originated independently.  One can work around the
vulnerability by setting environment variable OPENSSL_CONF to
"NUL:/openssl.cnf" or any other name that cannot exist as a file.
