CVSS: 9.1EPSS: 0%CPEs: 4EXPL: 1CVE-2017-11147 – php: Out-of-bounds read in phar_parse_pharfile
https://notcve.org/view.php?id=CVE-2017-11147
In PHP before 5.6.30 and 7.x before 7.0.15, the PHAR archive handler could be used by attackers supplying malicious archive files to crash the PHP interpreter or potentially disclose information due to a buffer over-read in the phar_parse_pharfile function in ext/phar/phar.c. En PHP anterior a versión 5.6.30 y versión 7.x anterior a 7.0.15, el manejador de archivos PHAR podría ser utilizado por archivos maliciosos suministrados por los atacantes para bloquear el intérprete PHP o potencialmente divulgar información debido a una lectura excesiva de búfer en la función phar_parse_pharfile en el archivo ext/phar/phar.c. • http://git.php.net/?p=php-src.git%3Ba=commit%3Bh=e5246580a85f031e1a3b8064edbaa55c1643a451 http://openwall.com/lists/oss-security/2017/07/10/6 http://php.net/ChangeLog-5.php http://php.net/ChangeLog-7.php http://www.securityfocus.com/bid/99607 https://access.redhat.com/errata/RHSA-2018:1296 https://bugs.php.net/bug.php?id=73773 https://security.netapp.com/advisory/ntap-20180112-0001 https://www.tenable.com/security/tns-2017-12 https://access.redhat.com/security/cve • CWE-20: Improper Input Validation CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=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. 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. Una lectura fuera de límites de la pila ocurre en la función match_at() durante la búsqueda de expresión regular. • http://www.securityfocus.com/bid/101244 https://access.redhat.com/errata/RHSA-2018:1296 https://github.com/kkos/oniguruma/commit/690313a061f7a4fa614ec5cc8368b4f2284e059b https://github.com/kkos/oniguruma/issues/57 https://access.redhat.com/security/cve/CVE-2017-9224 https://bugzilla.redhat.com/show_bug.cgi?id=1466730 • CWE-125: Out-of-bounds Read •

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 •

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.

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.
