CVE-2026-119718 - Blender 4.5.15 及 5.x 5.2.3 之前版本 Heap Buffer Overflow 漏洞
CVE-2026-119718 - Blender before 4.5.15 and 5.x before 5.2.3 Heap Buffer Overflow via Point Cache
Blender 4.5.15 及 5.x 5.2.3 之前版本存在 Heap Buffer Overflow 漏洞 - 核心缺陷 整數溢位導致堆緩衝區溢位 - 影響 攻擊者可利用自定義點快取檔案觸發崩潰或執行任意程式碼 - CVSS 3.1 HIGH - 緩解 更新至 4.5.15 或 5.2.3 以上版本。
此漏洞揭示 Blender 讀取點快取時的整數溢位，攻擊者可利用自定義檔案觸發崩潰或執行任意程式碼，提醒使用者及時升級並避免開啟不受信任的 .blend 檔案。
Blender before 4.5.15 and 5.x before 5.2.3 contains a heap buffer overflow vulnerability caused by integer overflow in ptcache_data_alloc() when reading point cache files. Attackers can supply a crafted point cache file with a large totpoint value alongside a .blend file to crash Blender or execute code as the user.
