| CVE-2017-9224 | 2 Oniguruma Project, Php | 2 Oniguruma, Php | 2022-07-20 | 7.5 HIGH | 9.8 CRITICAL |
| 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 | 2 Oniguruma Project, Php | 2 Oniguruma, Php | 2022-07-20 | 7.5 HIGH | 9.8 CRITICAL |
| 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 | 2 Oniguruma Project, Php | 2 Oniguruma, Php | 2022-07-20 | 7.5 HIGH | 9.8 CRITICAL |
| 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 | 2 Oniguruma Project, Php | 2 Oniguruma, Php | 2022-07-20 | 7.5 HIGH | 9.8 CRITICAL |
| 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-2019-13224 | 5 Canonical, Debian, Fedoraproject and 2 more | 5 Ubuntu Linux, Debian Linux, Fedora and 2 more | 2022-07-20 | 7.5 HIGH | 9.8 CRITICAL |
| A use-after-free in onig_new_deluxe() in regext.c in Oniguruma 6.9.2 allows attackers to potentially cause information disclosure, denial of service, or possibly code execution by providing a crafted regular expression. The attacker provides a pair of a regex pattern and a string, with a multi-byte encoding that gets handled by onig_new_deluxe(). Oniguruma issues often affect Ruby, as well as common optional libraries for PHP and Rust. | |||||
| CVE-2019-19012 | 4 Debian, Fedoraproject, Oniguruma Project and 1 more | 4 Debian Linux, Fedora, Oniguruma and 1 more | 2020-08-24 | 7.5 HIGH | 9.8 CRITICAL |
| An integer overflow in the search_in_range function in regexec.c in Oniguruma 6.x before 6.9.4_rc2 leads to an out-of-bounds read, in which the offset of this read is under the control of an attacker. (This only affects the 32-bit compiled version). Remote attackers can cause a denial-of-service or information disclosure, or possibly have unspecified other impact, via a crafted regular expression. | |||||
| CVE-2017-9225 | 3 Oniguruma Project, Php, Ruby-lang | 3 Oniguruma, Php, Ruby | 2017-06-02 | 7.5 HIGH | 9.8 CRITICAL |
| 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 onigenc_unicode_get_case_fold_codes_by_str() occurs during regular expression compilation. Code point 0xFFFFFFFF is not properly handled in unicode_unfold_key(). A malformed regular expression could result in 4 bytes being written off the end of a stack buffer of expand_case_fold_string() during the call to onigenc_unicode_get_case_fold_codes_by_str(), a typical stack buffer overflow. | |||||
