CVE-2017-9226

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 or read occurs in nextstateval() during regular expression compilation. Octal numbers larger than 0xff are not handled correctly in fetchtoken() and fetchtokenincc(). A malformed regular expression containing an octal number in the form of '\700' would produce an invalid code point value larger than 0xff in nextstateval(), resulting in an out-of-bounds write memory corruption.
