I've a hunch that there are a few issues with the changes. A quick
look at the patch shows that the change here breaks the preg_replace
call:
- $query_string = preg_replace("/(&trendhistory=)(\d+)/", "", $query_string);
+ $query_string = preg_replace("/(&trendhistory=)(\d+)/", "",
htmlspecialchars($query_string, ENT_QUOTES) );
It looks as if the htmlspecialchars call was misplaced. Not that it
is a security issue, but it's a bug.
Can anyone forward this upstream? I will try to take a look at the
rest of the patch later.
Cheers,
