The (1) htkreadheader, (2) alawinit, (3) ulawinit, (4) pcminit, (5) float32init, and (6) sdsreadheader functions in libsndfile 1.0.20 allow context-dependent attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted audio file.

Heap-based buffer overflow in aiffreadheader in libsndfile 1.0.15 through 1.0.19, as used in Winamp 5.552 and possibly other media programs, allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via an AIFF file with an invalid header value.

Heap-based buffer overflow in vocreadheader in libsndfile 1.0.15 through 1.0.19, as used in Winamp 5.552 and possibly other media programs, allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a VOC file with an invalid header value.

Integer overflow in libsndfile 1.0.18, as used in Winamp and other products, allows context-dependent attackers to execute arbitrary code via crafted description chunks in a CAF audio file, leading to a heap-based buffer overflow.

Heap-based buffer overflow in the flacbuffercopy 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.
