Echo: libsndfile: security update to 1.2.2-2+deb13u1+e1

high Tenable Cloud Security Plugin ID 457267

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-37555)

Solution

Update the libsndfile library and its related packages to version 1.2.2-2+deb13u1+e1 or later.
