Summary

In the ncnn framework, a vulnerability allows an out-of-bounds heap write. The issue occurs in ParamDict::load_param() when loading a malicious .param model file, as a negative parameter ID can index before the params[NCNN_MAX_PARAM_COUNT] array.

Risk Assessment

An attacker can remotely cause memory corruption, potentially leading to arbitrary code execution or system crash, compromising data confidentiality and integrity.

Recommendation

Immediately update ncnn to a version containing commit 5a0288f255daa6c3294f77109f67718e434ec020 or later.

Original NVD description (English source)

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.
