Published: 27 March 2025
Summary
CVE-2025-29487 is a high-severity Uncontrolled Resource Consumption (CWE-400) vulnerability in Libming Libming. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Application or System Exploitation (T1499.004); ranked in the top 35.0% 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 SC-5 (Denial-of-service Protection) and SI-10 (Information Input Validation).
Deeper analysis
CVE-2025-29487, published on 2025-03-27, is an out-of-memory error in the parseABC_STRING_INFO function of libming version 0.4.8. This flaw enables attackers to trigger a Denial of Service (DoS) condition through allocator exhaustion, as classified under CWE-400 (Uncontrolled Resource Consumption). The vulnerability carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H), highlighting its potential for significant availability disruption.
Attackers can exploit this vulnerability remotely over the network with low attack complexity, requiring no privileges, user interaction, or special scoping changes. Exploitation involves crafting malicious input that causes excessive memory allocation during parsing, leading to process crashes or resource exhaustion and denying service to legitimate users of affected libming-dependent applications.

Timely identification, reporting, and correction of flaws like the out-of-memory error in libming's parseABC_STRING_INFO directly prevents DoS exploitation by patching or removing the vulnerable component.
Validating inputs to the libming parser prevents malicious ABC_STRING_INFO data from triggering excessive memory allocation and allocator exhaustion.
Denial-of-service protections at system entry points mitigate remote network exploitation leading to process crashes from resource exhaustion in libming.
