Subject: Increase the precision of the nData parameter to the dbdataValue() routine
X-Git-Tag: version-3.40.0~10
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=92c0881d9d807549efd75b0235f5570e4a1f7a82;p=thirdparty%2Fsqlite.git

Increase the precision of the nData parameter to the dbdataValue() routine
inside the sqlite_dbdata virtual table, to avoid the possibility of integer
overflow.
