Other updates and bugfixes: - Non-CVE hardening taken from the same upstream release: * `sieve`: requiring the same extension repeatedly grew the default argument override chain, which is walked recursively - a crafted script could overflow the stack * `sieve`: `${unicode:...}` hex values could overflow an `unsigned int` and wrap back into the valid Unicode range; the hex parser also read one byte past the end of the buffer * `sieve` variables: the `${1234...}` numeric index overflowed a `signed int` * `sieve enotify`: a single script could emit an unlimited number of notification messages; limited to 10 as upstream does
