Description:
 An issue was discovered in Oniguruma 6.2.0, as used in Oniguruma-mod in
 Ruby through 2.4.1 and mbstring in PHP through 7.1.5. A heap out-of-bounds
 write occurs in bitset_set_range() during regular expression compilation
 due to an uninitialized variable from an incorrect state transition. An
 incorrect state transition in parse_char_class() could create an execution
 path that leaves a critical local variable uninitialized until it's used as
 an index, resulting in an out-of-bounds write memory corruption.
Ubuntu-Description:
 It was discovered that Oniguruma incorrectly handled certain regular
 expressions. An attacker could possibly use this issue to obtain
 sensitive information, cause a denial of service or execute arbitrary
 code.
