Integrity: Low
Availability: Low

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

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

Description

libsndfile through 1.2.2 has an ogg_vorbis.c vorbis_analysis_wrote out-of-bounds read.

Impact

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.

Base weaknessCWE Top 25 (2025): #8
The product reads data past the end, or before the beginning, of the intended buffer.
Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
Architecture and Design · Language Selection
Use a language that provides appropriate memory abstractions.
