New Comment:
With PHP-7.4 and Oniguruma 6.9.5, I get:
Warning: mb_ereg(): Pattern is not valid under UTF-8 encoding in â¦
So this issue appears to have been fixed. Since liboniguruma is
unbundled as of PHP 7.4.0, this ticket is obsolete anyway.

when it comes to security you guys completly ignore hosting where either dumb customers or hacked
customer sftp/ftp accounts place arbitary code
hecne as sysadmin you want as less as possible attack vectros on your system (no known bugs leading
to memory corruption to begin with, disable_functions, restrict access to shell binaries to force
disable exec and friends....)

This looks like an artificial pattern which is not likely to appear in common code, but has to be
specifically crafted to cause this specific problem. I don't think importing arbitrary patterns
and running them is a common scenario for PHP apps, and regular expressions are known to have
runaway patterns. So I don't think there is a security issue here. There might be a case for
adding some limits for recursion depth, etc. - I know PCRE has some but don't see much in
mbstring - but otherwise doesn't seem to be security issue here.

./php-7.2.13/sapi/cli/php -r
'var_dump(mb_ereg(file_get_contents("./out3/crashes/id:000000,sig:06,src:003281,op:havoc,rep:2"),""));'
