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. Se descubrió un problema en Oniguruma versión 6.2.0, tal como es usado en Oniguruma-mod en Ruby hasta la versión 2.4.1 y mbstring en PHP hasta la versión 7.1.5. • https://github.com/kkos/oniguruma/commit/166a6c3999bf06b4de0ab4ce6b088a468cc4029f https://github.com/kkos/oniguruma/issues/56 • CWE-787: Out-of-bounds Write •
CVSS: 9.8EPSS: 0%CPEs: 4EXPL: 1CVE-2017-9226 – oniguruma: Heap buffer overflow in next_state_val() during regular expression compilation
https://notcve.org/view.php?id=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. Un problema fue encontrado en Oniguruma versión 6.2.0, tal y como es usado en Oniguruma-mod en Ruby hasta la versión 2.4.1 y mbstring en PHP hasta la versión 7.1.5. • http://www.securityfocus.com/bid/101244 https://access.redhat.com/errata/RHSA-2018:1296 https://github.com/kkos/oniguruma/commit/b4bf968ad52afe14e60a2dc8a95d3555c543353a https://github.com/kkos/oniguruma/commit/f015fbdd95f76438cd86366467bb2b39870dd7c6 https://github.com/kkos/oniguruma/issues/55 https://access.redhat.com/security/cve/CVE-2017-9226 https://bugzilla.redhat.com/show_bug.cgi?id=1466736 • CWE-787: Out-of-bounds Write •
CVSS: 7.5EPSS: 0%CPEs: 6EXPL: 1CVE-2017-9229 – oniguruma: Invalid pointer dereference in left_adjust_char_head()
https://notcve.org/view.php?id=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. Se descubrió un problema en Oniguruma versión 6.2.0, como es usado en Oniguruma-mod en Ruby hasta versión 2.4.1 y mbstring en PHP hasta versión 7.1.5. Un SIGSEGV se produce en la función left_adjust_char_head() durante la compilación de expresiones regulares. • https://access.redhat.com/errata/RHSA-2018:1296 https://github.com/kkos/oniguruma/commit/b690371bbf97794b4a1d3f295d4fb9a8b05d402d https://github.com/kkos/oniguruma/issues/59 https://access.redhat.com/security/cve/CVE-2017-9229 https://bugzilla.redhat.com/show_bug.cgi?id=1466746 • CWE-476: NULL Pointer Dereference CWE-787: Out-of-bounds Write •

In MODX Revolution before 2.5.7, when PHP 5.3.3 is used, an attacker is able to include and execute arbitrary files on the web server due to insufficient validation of the action parameter to setup/index.php, aka directory traversal. En MODX Revolution anterior a versión 2.5.7, cuando se utiliza PHP versión 5.3.3, un atacante es capaz de incluir y ejecutar archivos arbitrarios en el servidor web debido a la comprobación insuficiente del parámetro action en el archivo setup/index.php, también se conoce como salto de directorio. • https://citadelo.com/en/2017/04/modx-revolution-cms https://github.com/modxcms/revolution/pull/13422 https://github.com/modxcms/revolution/pull/13428 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

The zend_string_extend function in Zend/zend_string.h in PHP through 7.1.5 does not prevent changes to string objects that result in a negative length, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact by leveraging a script's use of .= with a long string. La función zend_string_extend en el archivo Zend/zend_string.h en PHP hasta de la versión 7.1.5 no impide cambios en los objetos de cadena que resultan en una longitud negativa, lo que permite a los atacantes remotos causar una denegación de servicio (bloqueo de aplicación) o posiblemente tener otro impacto no especificado explotando el uso de scripts .= con una cadena larga. • http://www.securityfocus.com/bid/98518 https://bugs.php.net/bug.php?id=74577 • CWE-787: Out-of-bounds Write •
