sqlite 3.41 has a use-after-free vulnerability in the JSON parsing logic. Remote adversaries can craft malicious JSON payload to trigger memory free followed by illegal memory access, which may lead to arbitrary code execution, sensitive information leakage and service denial.
Weakness
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
