漏洞描述
中文描述:
Mbed TLS是Mbed TLS开源的一个开源、可移植、易于使用、可读且灵活的 SSL 库。 Mbed TLS 3.6.4之前版本存在资源管理错误漏洞，该漏洞源于释放后重用，可能导致空指针取消引用或双重释放。
英文描述:
Mbed TLS before 3.6.4 allows a use-after-free in certain situations of applications that are developed in accordance with the documentation. The function mbedtls_x509_string_to_names() takes a head argument that is documented as an output argument. The documentation does not suggest that the function will free that pointer; however, the function does call mbedtls_asn1_free_named_data_list() on that argument, which performs a deep free(). As a result, application code that uses this function (relying only on documented behavior) is likely to still hold pointers to the memory blocks that were freed, resulting in a high risk of use-after-free or double-free. In particular, the two sample programs x509/cert_write and x509/cert_req are affected (use-after-free if the san string contains more than one DN).
