+Subject: [PATCH] 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).
