NVD Description

Note: Versions mentioned in the description apply only to the upstream ruby1.8 package and not the ruby1.8 package as distributed by Ubuntu.

The parse_char_class function in regparse.c in the Onigmo (aka Oniguruma-mod) regular expression library, as used in Ruby 2.4.0, allows remote attackers to cause a denial of service (deep recursion and application crash) via a crafted regular expression.
