vorbis-tools, opus-tools -- multiple vulnerabilities

Paris Zoumpouloglou reports:

I discovered an integer overflow issue in oggenc,
related to the number of channels in the input WAV file.
The issue triggers an out-of-bounds memory access which
causes oggenc to crash.

Paris Zoumpouloglou reports:

A crafted WAV file with number of channels set to 0
will cause oggenc to crash due to a division by zero
issue.
