Unfortunately MITRE doesn't care about writing CVE descriptions that are useful for much longer past the time they're written. In other words, 1.0.30 is in the description, but MITRE doesn't care about misleading us into thinking versions greater than 1.0.30 are fixed.
I suppose this is the fix: commit deb669ee8be55a94565f6f8a6b60890c2e7c6f32 Author: bobsayshilol <bobsayshilol@live.co.uk> Date: Thu Feb 18 21:52:09 2021 +0000 ms_adpcm: Fix and extend size checks 'blockalign' is the size of a block, and each block contains 7 samples per channel as part of the preamble, so check against 'samplesperblock' rather than 'blockalign'. Also add an additional check that the block is big enough to hold the samples it claims to hold. https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=26803 The oss-fuzz issue shows the same size overwrite in the same function as the Github issue. Patch is only in the 1.1.0beta1 tag.

CVE-2021-4156 (https://bugzilla.redhat.com/show_bug.cgi?id=2027690): An out-of-bounds read flaw was found in libsndfile's FLAC codec functionality. An attacker who is able to submit a specially crafted file (via tricking a user to open or otherwise) to an application linked with libsndfile and using the FLAC codec, could trigger an out-of-bounds read that would most likely cause a crash but could potentially leak memory information that could be used in further exploitation of other flaws.
