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

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
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: 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).

Exploitation evidence

Disclosed: evidence found.
CVE published 28 Feb 2024
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

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

To mitigate CVE-2024-24147, organizations should first identify and inventory all systems and applications using libming, especially version 0.4.8. Until an official patch is released, consider the following specific measures: 1) Implement strict input validation and sandboxing for SWF file processing to isolate the parsing operation and limit memory usage; 2) Employ resource monitoring and limits (e.g., memory quotas, process timeouts) on applications handling SWF files to detect and terminate abnormal memory consumption; 3) Where feasible, disable or remove support for SWF file processing if it is not essential, given the declining use of Flash technology; 4) Use alternative, actively maintained libraries for SWF parsing that do not exhibit this vulnerability; 5) Educate users and administrators about the risks of opening or processing untrusted SWF files; 6) Monitor security advisories from libming maintainers for patches or updates addressing this issue and apply them promptly once available. Additionally, network-level controls such as blocking or filtering SWF files from untrusted sources can reduce exposure.

Description

A memory leak issue discovered in parseSWF_FILLSTYLEARRAY in libming v0.4.8 allows attackers to cause s denial of service via a crafted SWF file.

Impact

The primary impact of CVE-2024-24147 is denial of service through memory exhaustion. Organizations that rely on libming to parse or manipulate SWF files—such as multimedia processing tools, legacy Flash content handlers, or security scanners—may experience application crashes or degraded performance when processing malicious SWF files. This can disrupt business operations, especially in automated environments that handle large volumes of SWF content or user-submitted files. Although the vulnerability does not allow data theft or code execution, the availability impact can be significant in environments where uptime and reliability are critical. The lack of authentication requirements and the network attack vector increase the risk of exploitation, particularly in public-facing services that accept SWF files. However, the requirement for user interaction (processing the crafted file) somewhat limits automated exploitation. The absence of known exploits in the wild suggests limited current threat activity but does not preclude future attacks once exploit code becomes available.

CWE-401Missing Release of Memory after Effective Lifetime (opens in a new tab)
Variant weaknessLikelihood of exploit: Medium
The product does not sufficiently track and release allocated memory after it has been used, making the memory unavailable for reallocation and reuse.
Implementation · Libraries or Frameworks
Choose a language or tool that provides automatic memory management, or makes manual memory management less error-prone.
Architecture and Design
Use an abstraction library to abstract away risky APIs. Not a complete solution.
Architecture and Design · Build and Compilation
Consider using the Boehm-Demers-Weiser garbage collector (bdwgc), which can help avoid leaks.
