+Subject: rewrite wcsnrtombs to fix buffer overflow and other bugs
+
+the original wcsnrtombs implementation, which has been largely
+untouched since 0.5.0, attempted to build input-length-limiting
+conversion on top of wcsrtombs, which only limits output length. as
+best I recall, this choice was made out of a mix of disdain over
+having yet another variant function to implement (added in POSIX 2008;
+not standard C) and preference not to switch things around and
+implement the wcsrtombs in terms of the more general new function,
+probably over namespace issues. the strategy employed was to impose
+output limits that would ensure the input limit wasn't exceeded, then
+finish up the tail character-at-a-time. unfortunately, none of that
+worked correctly.
+
+first, the logic in the wcsrtombs loop was wrong in that it could
+easily get stuck making no forward progress, by imposing an output
+limit too small to convert even one character.
+
+the character-at-a-time loop that followed was even worse. it made no
+effort to ensure that the converted multibyte character would fit in
+the remaining output space, only that there was a nonzero amount of
+output space remaining. it also employed an incorrect interpretation
+of wcrtomb's interface contract for converting the null character,
+thereby failing to act on end of input, and remaining space accounting
+was subject to unsigned wrap-around. together these errors allow
+unbounded overflow of the destination buffer, controlled by input
+length limit and input wchar_t string contents.
+
+given the extent to which this function was broken, it's plausible
+that most applications that would have been rendered exploitable were
+sufficiently broken not to be usable in the first place. however, it's
+also plausible that common (especially ASCII-only) inputs succeeded in
+the wcsrtombs loop, which mostly worked, while leaving the wildly
+erroneous code in the second loop exposed to particular non-ASCII
+inputs.
+
+CVE-2020-28928 has been assigned for this issue.
