Heap-based Buffer Overflow in the psfbinheaderwritef function in common.c in libsndfile through 1.0.28 allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact.

A heap buffer overflow vulnerability in msadpcmdecodeblock of libsndfile 1.0.30 allows attackers to execute arbitrary code via a crafted WAV file.

In libsndfile version 1.0.28, an error in the "aiffreadchanmap()" function (aiff.c) can be exploited to cause an out-of-bounds read memory access via a specially crafted AIFF file.

A stack-based buffer overflow in psfmemset in common.c in libsndfile 1.0.28 allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted audio file. The vulnerability can be triggered by the executable sndfile-deinterleave.

The flacbuffercopy function in flac.c in libsndfile 1.0.28 allows remote attackers to cause a denial of service (buffer overflow and application crash) or possibly have unspecified other impact via a crafted audio file.

An issue was discovered in libsndfile 1.2.2 IMA ADPCM codec. The AIFF code path (line 241) was fixed with (sfcountt) cast, but the WAV code path (line 235) and close path (line 167) were not. When samplesperblock (int) blocks (int) exceeds INTMAX, the 32-bit multiplication overflows before being assigned to sf.frames (sfcountt/int64). With samplesperblock=50000 and blocks=50000, the product 2500000000 overflows to -1794967296. This causes incorrect frame count leading to heap buffer overflow or denial of service. Both values come from the WAV file header and are attacker-controlled. This issue was discovered after an incomplete fix for CVE-2022-33065.

An out of bounds read in the function d2ulawarray() in ulaw.c of libsndfile 1.0.28 may lead to a remote DoS attack or information disclosure, related to mishandling of the NAN and INFINITY floating-point values.

An out of bounds read in the function d2alawarray() in alaw.c of libsndfile 1.0.28 may lead to a remote DoS attack or information disclosure, related to mishandling of the NAN and INFINITY floating-point values.

An issue was discovered in libsndfile 1.0.28. There is a buffer over-read in the function i2alawarray in alaw.c that will lead to a denial of service.

CVE-2022-33065[0]: | Multiple signed integers overflow in function aureadheader in | src/au.c and in functions mat4open and mat4readheader 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 wavreadheader 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.

A buffer overflow vulnerability exists in libsndfile version 1.2.2 and potentially earlier versions when processing malformed IRCAM audio files. The vulnerability occurs in the ircamreadheader function at src/ircam.c:164 during sample rate processing, leading to memory corruption and potential code execution.

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.

libsndfile through 1.2.2 has a reachable assertion, that may lead to application exit, in mpegl3encode.c mpegl3encoderclose.

In libsndfile 1.0.28, a divide-by-zero error exists in the function double64init() in double64.c, which may lead to DoS when playing a crafted audio file.

In libsndfile 1.0.25 (fixed in 1.0.26), a divide-by-zero error exists in the function wavw64readfmtchunk() in wavw64.c, which may lead to DoS when playing a crafted audio file.

An issue was discovered in libsndfile 1.0.28. There is a NULL pointer dereference in the function sfwriteint in sndfile.c, which 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 i2ulawarray in ulaw.c that will lead to a denial of service.

The i2lesarray function in pcm.c in libsndfile 1.0.28 allows remote attackers to cause a denial of service (buffer over-read and application crash) via a crafted audio file.

The flacbuffercopy function in flac.c in libsndfile 1.0.28 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) via a crafted audio file.

The flacbuffercopy function in flac.c in libsndfile 1.0.28 allows remote attackers to cause a denial of service (invalid read and application crash) via a crafted audio file.

DISPUTED An issue has been found in libsndfile 1.0.28. There is a memory leak in psfallocate in common.c, as demonstrated by sndfile-convert. NOTE: The maintainer and third parties were unable to reproduce and closed the issue.

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 wavwriteheader() function in wav.c. A local attacker may use this flaw to make the application crash.

In libsndfile before 1.0.28, an error in the "flacbuffercopy()" function (flac.c) can be exploited to cause a segmentation violation (with read memory access) via a specially crafted FLAC file during a resample attempt, a similar issue to CVE-2017-7585.

In libsndfile before 1.0.28, an error in the "flacbuffercopy()" function (flac.c) can be exploited to cause a segmentation violation (with write memory access) via a specially crafted FLAC file during a resample attempt, a similar issue to CVE-2017-7585.

In libsndfile before 1.0.28, an error in the "headerread()" function (common.c) when handling ID3 tags can be exploited to cause a stack-based buffer overflow via a specially crafted FLAC file.

In libsndfile before 1.0.28, an error in the "flacbuffercopy()" function (flac.c) can be exploited to cause a stack-based buffer overflow via a specially crafted FLAC file.

Libsndfile <=1.2.2 contains a memory leak vulnerability in the mpegl3encoderinit() function within the mpegl3encode.c file.
