Memory Leak

** DISPUTED ** A segmentation fault can occur in the sqlite3.exe command-line component of SQLite 3.36.0

CVE-2021-36690 7.5 - High - August 24, 2021

** DISPUTED ** A segmentation fault can occur in the sqlite3.exe command-line component of SQLite 3.36.0 via the idxGetTableInfo function when there is a crafted SQL query. NOTE: the vendor disputes the relevance of this report because a sqlite3.exe user already has full privileges (e.g., is intentionally allowed to execute commands). This report does NOT imply any problem in the SQLite library.

A flaw was found in SQLite's SELECT query functionality (src/select.c)
