CVE-2025-52194

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 ircam_read_header function at src/ircam.c:164 during sample rate processing, leading to memory corruption and potential code execution.

• CVE-2025-52194: fix undefined behavior on float samplerate cast in ircam_read_header by using psf_lrintf (upstream 7ff854d1)

• CVE-2025-52194: fix undefined behavior on float samplerate cast in ircam_read_header by using psf_lrintf (upstream 7ff854d1)

• 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.

CVE-2025-52194 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 ircam_read_header function at src/ircam.c:164 during sample rate processing, leading to memory corruption and potential code execution. CVE-2025-56226 Libsndfile <=1.2.2 contains a memory leak vulnerability in the mpeg_l3_encoder_init() function within the mpeg_l3_encode.c file. CVE-2026-37555 An issue was discovered in libsndfile 1.2.2 IMA ADPCM codec. The AIFF code path (line 241) was fixed with (sf_count_t) cast, but the WAV code path (line 235) and close path (line 167) were not. When samplesperblock (int) * blocks (int) exceeds INT_MAX, the 32-bit multiplication overflows before being assigned to sf.frames (sf_count_t/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.

These are all security issues fixed in the libsndfile-devel-1.2.2-5.1 package on the GA media of openSUSE Tumbleweed.
