-Fix CVE-2017-12562
+commit cf7a8182c2642c50f1cf90dddea9ce96a8bad2e8

-See:
+    src/common.c: Fix heap buffer overflows when writing strings in binheader
     
-  https://nvd.nist.gov/vuln/detail/CVE-2017-12562
+    Fixes the following problems:
-  https://github.com/erikd/libsndfile/issues/292
+     1. Case 's' only enlarges the buffer by 16 bytes instead of size bytes.
+     2. psf_binheader_writef() enlarges the header buffer (if needed) prior to the
+        big switch statement by an amount (16 bytes) which is enough for all cases
+        where only a single value gets added. Cases 's', 'S', 'p' however
+        additionally write an arbitrary length block of data and again enlarge the
+        buffer to the required amount. However, the required space calculation does
+        not take into account the size of the length field which gets output before
+        the data.
+     3. Buffer size requirement calculation in case 'S' does not account for the
+        padding byte ("size += (size & 1) ;" happens after the calculation which
+        uses "size").
+     4. Case 'S' can overrun the header buffer by 1 byte when no padding is
+        involved
+        ("memcpy (&(psf->header.ptr [psf->header.indx]), strptr, size + 1) ;" while
+        the buffer is only guaranteed to have "size" space available).
+     5. "psf->header.ptr [psf->header.indx] = 0 ;" in case 'S' always writes 1 byte
+        beyond the space which is guaranteed to be allocated in the header buffer.
+     6. Case 's' can overrun the provided source string by 1 byte if padding is
+        involved ("memcpy (&(psf->header.ptr [psf->header.indx]), strptr, size) ;"
+        where "size" is "strlen (strptr) + 1" (which includes the 0 terminator,
+        plus optionally another 1 which is padding and not guaranteed to be
+        readable via the source string pointer).

+    a/ulaw: fix multiple buffer overflows (#432)
+    
+    i2ulaw_array() and i2alaw_array() fail to handle ptr [count] = INT_MIN
+    properly, leading to buffer underflow. INT_MIN is a special value
+    since - INT_MIN cannot be represented as int.
+    
+    In this case round - INT_MIN to INT_MAX and proceed as usual.
+    
+    f2ulaw_array() and f2alaw_array() fail to handle ptr [count] = NaN
+    properly, leading to null pointer dereference.
+    
+    In this case, arbitrarily set the buffer value to 0.
+    
+    This commit fixes #429 (CVE-2018-19661 and CVE-2018-19662) and
+    fixes #344 (CVE-2017-17456 and CVE-2017-17457).
