CVE-2007-4974
Heap-based buffer overflow in the flac_buffer_copy function in libsndfile 1.0.17 and earlier might allow remote attackers to execute arbitrary code via a FLAC file with crafted PCM data containing a block with a size that exceeds the previous block size.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.49%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
