Summary: | CVE-2017-9224;;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 read occurs in match_at() during regular expression;searching. A logical error involving order of validation and access in;match_at() could result in an out-of-bounds read from a stack buffer.;;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.

Description: | Summary: CVE-2017-9224 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 read occurs in match_at() during regular expression searching. A logical error involving order of validation and access in match_at() could result in an out-of-bounds read from a stack buffer. 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 next_state_val() during regular expression compilation. Octal numbers larger than 0xff are not handled correctly in fetch_token() and fetch_token_in_cc(). A malformed regular expression containing an octal number in the form of '\700' would produce an invalid code point value larger than 0xff in next_state_val(), resulting in an out-of-bounds write memory corruption. CVE-2017-9227 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 read occurs in mbc_enc_len() during regular expression searching. Invalid handling of reg->dmin in forward_search_range() could result in an invalid pointer dereference, as an out-of-bounds read from a stack buffer. CVE-2017-9228 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. CVE-2017-9229 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 SIGSEGV occurs in left_adjust_char_head() during regular expression compilation. Invalid handling of reg->dmax in forward_search_range() could result in an invalid pointer dereference, normally as an immediate denial-of-service condition. Affected Software/OS: libonig on Debian Linux Solution: For Debian 7 'Wheezy', these problems have been fixed in version 5.9.1-1+deb7u1. We recommend that you upgrade your libonig packages.
