漏洞描述

TFlite graphs must not have loops between nodes. However, this condition was not checked and an attacker could craft models that would result in infinite loop during evaluation. In certain cases, the infinite loop would be replaced by stack overflow due to too many recursive calls.

解决建议

建议您更新当前系统或软件至最新版，完成漏洞的修复。
