Multiple signed integers overflow in function au_read_header in src/au.c and in functions mat4_open and mat4_read_header in src/mat4.c in Libsndfile, allows an attacker to cause Denial of Service or other unspecified impacts.
An off-by-one error in function wav_read_header in src/wav.c in Libsndfile 1.1.0, results in a write out of bound, which allows an attacker to execute arbitrary code, Denial of Service or other unspecified impacts.
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.
It was discovered the fix for CVE-2018-19758 (libsndfile) was not complete and still allows a read beyond the limits of a buffer in wav_write_header() function in wav.c. A local attacker may use this flaw to make the application crash.
An issue was discovered in libsndfile 1.0.28. There is a buffer over-read in the function i2ulaw_array in ulaw.c that will lead to a denial of service.
An issue was discovered in libsndfile 1.0.28. There is a buffer over-read in the function i2alaw_array in alaw.c that will lead to a denial of service.
