                    <description>&lt;p&gt;An internal audit has discovered the following security vulnerability, so would you kindly consider addressing this:&lt;/p&gt;

&lt;p&gt;Apologies for the delay in responding. I&apos;m currently looking into two potential solutions:&lt;/p&gt;
&lt;ol&gt;
	&lt;li&gt;Specify the full path. This may be a backwards-breaking behavioral change, but secur32.dll is a system library, not a custom one that we provide, so it might be OK for us to only look for it in the standard system paths. I&apos;m currently looking into where this library is DLL is located and whether that location differs in various Windows versions.&lt;/li&gt;
	&lt;li&gt;Use either LoadLibraryExA or LoadLibraryExW with the&#160;LOAD_LIBRARY_SEARCH_SYSTEM32 flag, which would only allow the linker to look for those libraries in system directories. That flag is not supported on Windows XP, however, so I&apos;m also figuring out if that would be a reasonable restriction.&lt;/li&gt;
&lt;/ol&gt;


&lt;p&gt;Once we&apos;ve designed on a path forward, I&apos;ll update this ticket.&lt;/p&gt;
