Summary
CVE-2025-26305 is a high-severity Heap Inspection (CWE-244) vulnerability in Libming Libming. Its CVSS base score is 8.2 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 44.5% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Requires timely remediation of the specific memory leak flaw in libming's parseSWF_SOUNDINFO function to eliminate the vulnerability.
Mandates validation of SWF file inputs prior to parsing to block crafted files that trigger the memory leak.
Provides memory protection mechanisms that mitigate heap memory leaks and potential information disclosure from improper memory clearing.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Remote unauthenticated exploitation via crafted SWF input to a network-accessible parser directly matches T1190.
NVD Description
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.
Deeper analysisAI
CVE-2025-26305 is a memory leak vulnerability in the parseSWF_SOUNDINFO function within util/parser.c of libming version 0.4.8. This issue affects the libming library, which handles parsing of Macromedia Flash (SWF) files, and is classified under CWE-244 (Improper Clearing of Heap Memory Before Release). The vulnerability was published on 2025-02-20 and carries a CVSS v3.1 base score of 8.2 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N), highlighting its high severity due to network accessibility and low attack complexity.
Remote attackers require no privileges or user interaction to exploit this flaw by supplying a specially crafted SWF file to a vulnerable libming instance. Successful exploitation triggers the memory leak, enabling a denial of service through resource exhaustion, while the high confidentiality impact indicates potential leakage of sensitive information from heap memory and low integrity impact from possible memory corruption.
