+Subject: [PATCH] FLAC: Fix a buffer read overrun
+
+Buffer read overrun occurs when reading a FLAC file that switches
+from 2 channels to one channel mid-stream. Only option is to
+abort the read.

+Subject: [PATCH] src/flac.c: Fix a buffer read overflow
+
+A file (generated by a fuzzer) which increased the number of channels
+from one frame to the next could cause a read beyond the end of the
+buffer provided by libFLAC. Only option is to abort the read.
