An exploitable use after free vulnerability exists in the window function functionality of Sqlite3 3.26.0. A specially crafted SQL command can cause a use after free vulnerability, potentially resulting in remote code execution. An attacker can send a malicious SQL command to trigger this vulnerability.
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 Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
