CVE-2025-26311 has been identified in the libming library, specifically affecting version 0.4.8. This vulnerability allows attackers to exploit multiple memory leaks in the clip actions parsing functions, namely parseSWF_CLIPACTIONS and parseSWF_CLIPACTIONRECORD. By crafting a malicious SWF file, an attacker can trigger these memory leaks, leading to a denial of service (DoS). Given its potential impact, understanding the severity and risk associated with this vulnerability is crucial for organizations relying on libming.
The CVSS score for this vulnerability is 6.5, indicating a medium severity level. The attack vector is classified as network-based, requiring low complexity and no privileges to exploit. However, user interaction is necessary, as an unsuspecting user must open the malicious SWF file for the attack to be successful. The potential impact on availability is high, meaning systems could become unavailable if this vulnerability is successfully exploited.
Organizations should prioritize addressing this vulnerability in their patching cycles. The risk posed by this vulnerability is significant, as a successful denial of service attack can disrupt services and impact user experience.
Currently, there is no known public exploit for this vulnerability, and it is not included in the Known Exploited Vulnerabilities (KEV) catalog. However, given the nature of the vulnerabilities and the potential for exploitation, organizations should remain vigilant.
Organizations should prioritize patching immediately.
Vulnerability Details
This vulnerability allows multiple memory leaks to occur in the clip actions parsing functions of libming. The affected version is 0.4.8, and it has been classified under CWE-401, which signifies a memory leak issue. The official description states that attackers can cause a denial of service via a crafted SWF file.
The vulnerability has a CVSS score of 6.5, indicating a medium severity. The attack vector is network-based, complexity is low, and no privileges are required to exploit it. User interaction is required, which means that an attacker must convince a user to open the malicious SWF file for the attack to succeed.
Technical Analysis
The root cause of CVE-2025-26311 lies in the memory management practices within the libming library. Specifically, the parseSWF_CLIPACTIONS and parseSWF_CLIPACTIONRECORD functions fail to properly manage memory allocations, leading to leaks. The attack vector for this vulnerability is network-based, as it requires an attacker to deliver a malicious SWF file to a target system.
The attack complexity is classified as low, as it does not require any special conditions or permissions to exploit. Attackers do not need any privileges, and the only requirement is for the user to open the crafted SWF file. This lack of required privileges makes it easier for an attacker to exploit this vulnerability.
The potential impacts of this vulnerability primarily affect availability. If the memory leak is exploited, it can lead to a denial of service, rendering the application unusable. This could have significant implications for organizations relying on libming for their operations.
Risk & Impact Analysis
The real-world risk posed by CVE-2025-26311 is substantial. Organizations that utilize libming for processing SWF files may face service disruptions if this vulnerability is exploited. The blast radius could affect any user who interacts with the application utilizing this library, especially if they are tricked into opening a malicious SWF file.
Given its medium severity, organizations should assess their exposure and the impact of potential denial of service situations. The urgency for remediation is moderate; organizations should schedule this vulnerability for remediation in their patching cycles.
