+Subject: [PATCH] matroskademux: Avoid integer-overflow resulting in heap
+ corruption in WavPack header handling code
+
+blocksize + WAVPACK4_HEADER_SIZE might overflow gsize, which then
+results in allocating a very small buffer. Into that buffer blocksize
+data is memcpy'd later which then causes out of bound writes and can
+potentially lead to anything from crashes to remote code execution.
+
+Thanks to Adam Doupe for analyzing and reporting the issue.

+Subject: [PATCH] matroskademux: Fix integer overflows in zlib/bz2/etc
+ decompression code
+
+Various variables were of smaller types than needed and there were no
+checks for any overflows when doing additions on the sizes. This is all
+checked now.
+
+In addition the size of the decompressed data is limited to 120MB now as
+any larger sizes are likely pathological and we can avoid out of memory
+situations in many cases like this.
+
+Also fix a bug where the available output size on the next iteration in
+the zlib/bz2 decompression code was provided too large and could
+potentially lead to out of bound writes.
+
+Thanks to Adam Doupe for analyzing and reporting the issue.
