CVE-2025-5203:
Linux Debian vulnerability analysis and mitigation
Overview
A vulnerability has been identified in Open Asset Import Library (Assimp) version 5.4.3, tracked as CVE-2025-5203. The issue affects the SkipSpaces function in the library assimp/include/assimp/ParsingUtils.h, which can lead to an out-of-bounds read vulnerability. The vulnerability was discovered and disclosed on May 26, 2025 (NVD).
Technical details
The vulnerability stems from a heap buffer overflow condition in the SkipSpaces function. The issue occurs because the while loop condition performs pointer dereferencing before checking the pointer bounds. This pattern appears in multiple locations within the ParsingUtils.h file, including lines 106, 122, 127, and 143. The vulnerability has been assigned a CVSS v4.0 score of 4.8 (MEDIUM) with the vector string CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N (GitHub Issue).
Impact
The vulnerability results in an out-of-bounds read condition, which could potentially lead to information disclosure or program crashes. The issue requires local access to be exploited, which somewhat limits its potential impact (NVD).
Mitigation and workarounds
The project has acknowledged the issue and has decided to collect all Fuzzer bugs in a main issue to address them in the future. Currently, there is no official patch available for this vulnerability (NVD).
