Vulnerability Title
ncnn: Out-of-bounds heap write in ParamDict::load_param via unchecked negative parameter id
Vulnerability Description
ncnn is a high-performance neural network inference framework optimized for the mobile platform. In commit e54f7b1f88434e1d844ea0551b880a1cfb079ce1 and earlier, ncnn allows an out-of-bounds heap write in ncnn::ParamDict::load_param() when Net::load_param() loads a malicious .param model file because the parsed parameter id is checked only against id >= NCNN_MAX_PARAM_COUNT, allowing a negative id to index before the params[NCNN_MAX_PARAM_COUNT] array. This vulnerability is fixed by commit 5a0288f255daa6c3294f77109f67718e434ec020.

Vulnerability Title
Tencent ncnn 输入验证错误漏洞
Vulnerability Description
Tencent ncnn是中国Tencent公司开源的一款高性能神经网络前向计算框架。 Tencent ncnn存在安全漏洞,该漏洞源于ncnn::ParamDict::load_param()函数中参数ID检查不充分,仅检查id >= NCNN_MAX_PARAM_COUNT,导致允许负数ID对params数组进行越界索引,当Net::load_param()加载恶意.param模型文件时可能造成堆越界写入。以下版本受到影响:5a0288f255daa6c3294f77109f67718e434ec02
