Updated libsndfile packages fix security vulnerabilities

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.
