Subject: [PATCH] Actually fail when error occurs in parseFormat
|
|
|
|
When there's an unsupported number of bits per sample or an invalid
|
|
number of samples per block, don't only print an error message using
|
|
the error handler, but actually stop parsing the file.
|
|
|
|
This fixes #35 (also reported at
|
|
https://bugzilla.opensuse.org/show_bug.cgi?id=1026983 and
|
|
https://blogs.gentoo.org/ago/2017/02/20/audiofile-heap-based-buffer-overflow-in-imadecodeblockwave-ima-cpp/
