Overview

An allocation-size-too-big error in the parseSWF_DEFINEBINARYDATA function of libming v0.48 allows attackers to cause a Denial of Service (DoS) via supplying a crafted SWF file. The vulnerability was discovered and disclosed on March 27, 2025, affecting libming version 0.48 (NVD).

Technical details

The vulnerability occurs in the parseSWF_DEFINEBINARYDATA function when attempting to allocate an excessively large block of memory that exceeds the maximum supported size by the allocator. The issue is triggered during the parsing of SWF files containing binary data, leading to a failed memory allocation request and causing the application to abort. The vulnerability has been assigned a CVSS v3.1 base score of 6.5 (Medium) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H, and is classified as CWE-789 (Memory Allocation with Excessive Size Value) (NVD).

Impact

When successfully exploited, this vulnerability can lead to Denial of Service (DoS) conditions by causing the application to abort due to failed memory allocation requests. This affects the availability of systems processing SWF files using libming (NVD).
