CVE-2026-119719：Blender 4.5.15 及 5.x 5.2.3 前版本 Heap Buffer Overflow 漏洞
CVE-2026-119719 - Blender before 4.5.15 and 5.x before 5.2.3 Heap Buffer Overflow via Thumbnail Extraction
Blender 4.5.15 及 5.x 5.2.3 前版本因 thumbnail 提取器中的 32 位整數溢位而存在 Heap Buffer Overflow 漏洞，攻擊者可利用此漏洞在預覽 .blend 檔案時觸發崩潰或執行任意程式。
此漏洞可能導致 Blender 前版本使用者在預覽 .blend 檔案時崩潰或執行任意程式，使用者須即時升級以避免風險。
Blender before 4.5.15 and 5.x before 5.2.3 contains a heap buffer overflow vulnerability in the blend file thumbnail extractor caused by 32-bit integer overflow in thumb_data_vertical_flip(). Attackers can craft a .blend file with malicious TEST block dimensions that trigger an out-of-bounds write when blender-thumbnailer or the Windows shell extension previews it, causing crashes or code execution.
