CVE-2025-26305 is a high-severity vulnerability discovered in libming, specifically in version 0.4.8. This vulnerability allows attackers to exploit a memory leak present in the parseSWF_SOUNDINFO function located in util/parser.c. By crafting malicious SWF files, attackers can trigger a denial of service, significantly impacting the availability of the affected system.
The CVSS score for this vulnerability is 8.2, classifying it as high severity. The attack vector is network-based, requiring low complexity and no privileges or user interaction to exploit. Given the potential for denial of service, organizations using libming should prioritize remediation efforts.
Currently, there are no known exploits that leverage this vulnerability, but the implications of denial of service make it crucial for organizations to address it promptly. Organizations should be aware of the risks and take necessary actions to mitigate potential impacts.
Organizations should prioritize patching immediately to safeguard their systems against this vulnerability.
Vulnerability Details
The official description of CVE-2025-26305 states that a memory leak has been identified in the parseSWF_SOUNDINFO function in util/parser.c of libming v0.4.8, which allows attackers to cause a denial of service via a crafted SWF file. The CWE classification associated with this vulnerability is CWE-244.
The attack vector for this vulnerability is classified as network, with low attack complexity. No privileges are required, and user interaction is not needed to exploit this vulnerability. The impacts are categorized as high for confidentiality, low for integrity, and none for availability.
This vulnerability was published on February 20, 2025, and is currently in an analyzed status.
Organizations using libming v0.4.8 should take immediate action to patch their systems to the latest version to mitigate this vulnerability.
Technical Analysis
The root cause of CVE-2025-26305 is a memory leak in the parsing function for SWF files within libming. Attackers can exploit this vulnerability by sending specially crafted SWF files that trigger the memory leak, leading to a denial of service condition.
This vulnerability does not require any user interaction, making it easier for attackers to exploit it remotely. Given its network attack vector and the low complexity required for exploitation, it poses a significant risk.
The impact on confidentiality is high due to the unauthorized access to sensitive data that could arise from a successful exploit, while the integrity impact is low. Availability is notably affected, as the denial of service directly disrupts normal operations.
Risk & Impact Analysis
Risk to organizations includes potential downtime and disruption of services due to the denial of service caused by this vulnerability. The blast radius of this vulnerability could extend to all users of the affected libming version, impacting service availability and user trust.
Organizations should assess their deployment of libming and the potential for exposure to this vulnerability. Given the high CVSS score and the lack of available fixes at present, addressing this vulnerability should be considered a priority.
The exploitability score indicates a moderate to high risk, urging organizations to take swift action to remediate the vulnerability.

Affected Versions
The affected version of libming is 0.4.8. All versions prior to vendor patch are also considered vulnerable.
Mitigation & Remediation
Organizations should prioritize patching immediately. It is essential to update to the latest version of libming that addresses this memory leak vulnerability. If a patch is unavailable, organizations should review their configurations and implement network controls to limit exposure.
Configuration hardening should also be applied to minimize potential attack vectors. Regular monitoring of system logs may help detect any attempts to exploit this vulnerability.
Penetration testing can also help validate the effectiveness of the remediation efforts.
Detection Guidance
To detect potential exploitation of CVE-2025-26305, organizations should monitor for unusual memory consumption patterns in their applications. Log indicators that show abnormal behavior during SWF file processing may also serve as early warning signs of an active attack.
Behavioral anomalies during file parsing and network signatures indicative of crafted SWF file transfers should be closely examined. System changes that coincide with SWF file uploads may also warrant investigation.
AppSecure Threat Intelligence Insight
