CVE-2024-50612 is an out-of-bounds read vulnerability found in libsndfile, a widely used open-source library for reading and writing audio files. Specifically, the flaw exists in the ogg_vorbis.c source file within the vorbis_analysis_wrote function. This function improperly accesses memory beyond the bounds of allocated buffers when processing Ogg Vorbis audio data, leading to a potential out-of-bounds read condition (CWE-125). Such a vulnerability can cause the application to read unintended memory areas, potentially leaking sensitive information or causing application crashes. The vulnerability affects libsndfile versions through 1.2.2, with no specific patch currently linked. The CVSS 3.1 base score is 5.3, reflecting a medium severity level. The attack vector is local (AV:L), meaning an attacker must have local access to the system, and user interaction is required (UI:R), such as opening or processing a maliciously crafted audio file. No privileges are required (PR:N), and the scope is unchanged (S:U). The impact affects confidentiality, integrity, and availability to a limited extent (C:L/I:L/A:L). No known exploits have been reported in the wild, but the vulnerability poses a risk to applications that process untrusted Ogg Vorbis audio files using libsndfile. This includes multimedia players, audio editing software, and other systems that rely on this library for audio decoding and encoding.

The vulnerability could allow an attacker with local access to cause an application using libsndfile to read memory out-of-bounds when processing a crafted Ogg Vorbis audio file. This may lead to information disclosure if sensitive memory contents are exposed, or application instability and crashes, potentially resulting in denial of service. While the attack requires local access and user interaction, the impact on confidentiality, integrity, and availability is moderate but not critical. Organizations that handle untrusted audio files or provide audio processing capabilities could see disruptions or data leakage. Systems embedded in multimedia environments, audio editing tools, or software that automatically processes audio files are at risk. The absence of known exploits reduces immediate threat but does not eliminate future risk, especially as exploit development could emerge once the vulnerability becomes widely known. The lack of an available patch increases the urgency for interim mitigations.

1. Monitor official libsndfile repositories and security advisories for patches addressing CVE-2024-50612 and apply updates promptly once available. 2. Implement strict input validation and sanitization for all audio files, especially Ogg Vorbis files, to detect and block malformed or suspicious content before processing. 3. Employ sandboxing or containerization techniques to isolate applications using libsndfile, limiting the impact of potential crashes or memory disclosures. 4. Restrict local access to systems processing untrusted audio files to trusted users only, reducing the attack surface. 5. Use application-level logging and monitoring to detect abnormal crashes or behavior indicative of exploitation attempts. 6. Where possible, replace or supplement libsndfile with alternative libraries that do not exhibit this vulnerability until a patch is released. 7. Educate users about the risks of opening untrusted audio files and encourage cautious handling of such content.
