CVE-2022-33065

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.

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.

Libsndfile is a C library for reading and writing files containing sampled sound such as MS Windows WAV and the Apple/SGI AIFF format through one standard library interface.

Security Fix(es):

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.(CVE-2022-33065)

libsndfile is a C library for reading and writing files containing sampled sound, such as AIFF, AU, or WAV.

Security Fix(es):

• libsndfile: integer overflow in src/mat4.c and src/au.c leads to DoS (CVE-2022-33065)

• CVE-2022-33065: fix int overflow in dataend calculation

• CVE-2022-33065: fix multiple signed integer overflows in au.c, mat4.c and mat5.c

• SECURITY UPDATE: multiple signed integer overflows in the AU, MAT4/MAT5, AVR, SDS, AIFF, IRCAM, RF64, PCM and IMA-ADPCM header parsers allow denial of service via a crafted file (ELSCVE-171688)
  • debian/patches/CVE-2022-33065/CVE-2022-33065-{1..8,11..13}.patch: widen the overflowing data_end, blockwidth and sample-count calculations to sf_count_t in src/au.c, src/mat4.c, src/mat5.c, src/avr.c, src/sds.c, src/aiff.c, src/ircam.c, src/common.h, src/common.c, src/pcm.c, src/rf64.c and src/ima_adpcm.c. Byte-identical to Ubuntu's own patches as shipped in the public focal security source 1.0.28-7ubuntu0.3 (same upstream 1.0.28, same 13-patch prefix); the bionic +esm1 artifact itself is Ubuntu Pro-gated. Note that Ubuntu's CVE-2022-33065-13.patch is a squash of three upstream commits rather than the single one its header names: 3970faeb (IMA ADPCM nibble sizing) and 7e6cc7cb (stepindx initialisation) are prerequisites that 1.0.28 predates, alongside the cited 9f097e49 which carries the CVE-2022-33065 fix proper; all three are credited in that patch's provenance note.
  • CVE-2022-33065
• SECURITY UPDATE: out-of-bounds read in the FLAC decoder when a frame fails to decode and the stale frame pointer is reused (ELSCVE-171682)
  • debian/patches/CVE-2021-4156.patch: NULL pflac->frame when FLAC__stream_decoder_process_single() fails in flac_read_loop() in src/flac.c. Byte-identical to Ubuntu's own patch as shipped in the public focal security source 1.0.28-7ubuntu0.3; upstream commit ced91d7b971be6173b604154c39279ce90ad87cc.
  • CVE-2021-4156
• SECURITY UPDATE: undefined float-to-int conversion of the IRCAM header sample rate on out-of-range or non-finite values (ELSCVE-171686)
  • debian/patches/CVE-2025-52194.patch: convert the file-supplied sample rate with lrintf() instead of a bare (int) cast in ircam_read_header() in src/ircam.c, and include <math.h>. Backport of upstream commit 7ff854d1e0bd9a751a9ff52ed980c62afced91fe, adapted because 1.0.28 has no psf_lrintf() helper; src/mat4.c already uses lrint() for the same purpose in this tree.

Add upstream patch to fix CVE-2022-33065

These are all security issues fixed in the libsndfile-devel-1.2.2-1.1 package on the GA media of openSUSE Tumbleweed.

This update for libsndfile fixes the following issues:

• CVE-2022-33065: Fixed an integer overflow that could cause memory safety issues when reading a MAT4 file (bsc#1213451).

This update for libsndfile fixes the following issues:

• CVE-2022-33065: Fixed an integer overflow that could cause memory safety issues when reading a MAT4 file (bsc#1213451).

It was discovered that libsndfile contained multiple arithmetic overflows. If a user or automated system were tricked into processing a specially crafted audio file, an attacker could possibly use this issue to cause a denial of service.
