+Description: Fix CVE-2017-9258, CVE-2017-9259, CVE-2017-9260
+ Based on an upstream commit, original commit message was: "Added sanity
+ checks against illegal input audio stream parameters e.g. wildly excessive
+ samplerate".
+ . 
+ There is no reference to CVEs or bugs, the commit was made after disclosure
+ of the CVEs and all three proofs of concept (crafted wav files) fail after
+ this commit.
+ . 
+ The commit was made after version 2.0.0, so that version is also vulnerable.
+ .
+ Unrelated changes were stripped away by patch author, upstream commit author
+ is Olli Parviainen <[email protected]>.
