  "details": "DBD::Pg version 3.21.0 for Perl has a heap out-of-bounds write in quote_float.\n\nquote_float() allocates the length of the string + 1, which is the size of the bare numeric symbol plus NULL.  But for special literals NaN, Inf, +Inf, -Inf, Infinity, +Infinity, -Infinity it emits the literal surrounded by quotes plus NULL, which is length + 3 bytes. Every recognised literal (case-insensitive) overflows by 2 bytes, a single quote and a NULL.\n\nThis can be reached by the $dbh-\u003equote method, for example\n\n    $dbh-\u003equote( \"Infinity\", DBI::SQL_NUMERIC ).\n\nThis regression was introduced in 3.21.0 by the quote.c rewrite.",
