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 stack out-of-bounds write in onigencunicodegetcasefoldcodesbystr() occurs during regular expression compilation. Code point 0xFFFFFFFF is not properly handled in unicodeunfoldkey(). A malformed regular expression could result in 4 bytes being written off the end of a stack buffer of expandcasefoldstring() during the call to onigencunicodegetcasefoldcodesby_str(), a typical stack buffer overflow.
