Confidentiality: None
Integrity: None
Availability: High

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: None: The vulnerable system can be exploited without any interaction from any user.
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: None: There is no loss of confidentiality within the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

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 2026-10-26.

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 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

In the interim, restrict or sanitize media inputs to FFmpeg, especially from untrusted or external sources, to reduce the risk of processing malicious files. Implement sandboxing or containerization for media processing components to limit the impact of potential crashes or undefined behavior. Employ input validation and filtering mechanisms to detect and block malformed or suspicious media files before they reach FFmpeg. Additionally, maintain robust monitoring and logging around media processing services to detect abnormal crashes or service disruptions indicative of exploitation attempts. Where possible, upgrade to newer FFmpeg versions that have addressed this vulnerability or disable the DXA demuxer if it is not required for operational needs. Educate developers and system administrators about the risks of integer overflows and the importance of secure media handling practices.

Description

FFmpeg n6.1.1 has a vulnerability in the DXA demuxer of the libavformat library allowing for an integer overflow, potentially resulting in a denial-of-service (DoS) condition or other undefined behavior.

Impact

The primary impact of CVE-2024-36613 is denial-of-service, which can disrupt media processing workflows, streaming services, or any application relying on FFmpeg for multimedia handling. This can lead to service outages, degraded user experience, or operational interruptions. Although confidentiality and integrity are not directly affected, availability issues can have downstream effects on business continuity and service reliability. Organizations that ingest or transcode large volumes of media, such as broadcasters, content delivery networks, and cloud service providers, may face increased risk if attackers supply malicious media files. The vulnerability could also be leveraged as part of a broader attack chain to cause instability or distract defenders. Since exploitation requires local access to supply malicious input, environments where users can upload or process untrusted media files are particularly vulnerable. The absence of known exploits and the medium severity rating suggest the threat is moderate but warrants proactive mitigation to prevent future exploitation.

CWE-190Integer Overflow or Wraparound (opens in a new tab)
Base weaknessLikelihood of exploit: Medium
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
Requirements
Ensure that all protocols are strictly defined, such that all out-of-bounds behavior can be identified simply, and require strict conformance to the protocol.
Requirements · Language Selection
Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
