CVE-2021-4156

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.
