+Subject: iconv: fix erroneous input validation in EUC-KR decoder
+
+as a result of incorrect bounds checking on the lead byte being
+decoded, certain invalid inputs which should produce an encoding
+error, such as "\xc8\x41", instead produced out-of-bounds loads from
+the ksc table.
+
+in a worst case, the loaded value may not be a valid unicode scalar
+value, in which case, if the output encoding was UTF-8, wctomb would
+return (size_t)-1, causing an overflow in the output pointer and
+remaining buffer size which could clobber memory outside of the output
+buffer.
+
+bug report was submitted in private by Nick Wellnhofer on account of
+potential security implications.

+Subject: iconv: harden UTF-8 output code path against input decoder bugs
+
+the UTF-8 output code was written assuming an invariant that iconv's
+decoders only emit valid Unicode Scalar Values which wctomb can encode
+successfully, thereby always returning a value between 1 and 4.
+
+if this invariant is not satisfied, wctomb returns (size_t)-1, and the
+subsequent adjustments to the output buffer pointer and remaining
+output byte count overflow, moving the output position backwards,
+potentially past the beginning of the buffer, without storing any
+bytes.
