AI-suggested
This vulnerability is fixed in Blender versions 4.5.15 and 5.2.3. Users should update to these versions or later to remediate the issue. No other mitigation is indicated by the vendor advisory.
Description
Blender versions before 4.5.15 and 5.x before 5.2.3 have a heap buffer overflow vulnerability due to an integer overflow in the ptcache_data_alloc() function when reading point cache files. An attacker can craft a malicious point cache file with a large totpoint value alongside a .blend file to cause a crash or potentially execute arbitrary code with user privileges.
