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.

Security issues from bundled oniguruma in php-mbstring (CVE-2017-9224, CVE-2017-9226, CVE-2017-9227, CVE-2017-9228, CVE-2017-9229).

This update for php53 fixes the following issues:

This security issue was fixed:

• CVE-2017-7272: PHP enabled potential SSRF in applications that accept an fsockopen hostname argument with an expectation that the port number is constrained. Because a :port syntax was recognized, fsockopen used the port number that is specified in the hostname argument, instead of the port number in the second argument of the function (bsc#1031246)
• CVE-2016-6294: The locale_accept_from_http function in ext/intl/locale/locale_methods.c did not properly restrict calls to the ICU uloc_acceptLanguageFromHTTP function, which allowed remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a call with a long argument (bsc#1035111).
• CVE-2017-9227: An issue was discovered in Oniguruma 6.2.0, as used in mbstring in PHP. 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. (bsc#1040883)
• CVE-2017-9226: An issue was discovered in Oniguruma 6.2.0, as used in Oniguruma-mod in mbstring in PHP. 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. (bsc#1040889)
• CVE-2017-9224: An issue was discovered in Oniguruma 6.2.0, as used in Oniguruma-mod in mbstring in PHP. 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. (bsc#1040891)

This update for php5 fixes the following security issues:

• CVE-2016-6294: The locale_accept_from_http function in ext/intl/locale/locale_methods.c did not properly restrict calls to the ICU uloc_acceptLanguageFromHTTP function, which allowed remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a call with a long argument (bsc#1035111).
• CVE-2017-9227: A stack out-of-bounds read occurs in mbc_enc_len() during regular expression searching. (bsc#1040883)
• CVE-2017-9226: A heap out-of-bounds write or read occurs in next_state_val() during regular expression compilation. (bsc#1040889)
• CVE-2017-9224: A stack out-of-bounds read occurs in match_at() during regular expression searching. (bsc#1040891)

This update for php7 fixes the following security issues:

• CVE-2017-9224: stack out-of-bounds read occurs in match_at() could lead to Denial of service (bsc#1040891)
• CVE-2017-9226: heap out-of-bounds write orread occurs in next_state_val() could lead to Denial of service(bsc#1040889)
• CVE-2017-9227: stack out-of-bounds read in mbc_enc_len() could lead to Denial of service (bsc#1040883)
• CVE-2017-6441: The _zval_get_long_func_ex in Zend/zend_operators.c in PHP allowed attackers to cause a denial of service (NULL pointer dereference and application crash) via crafted use of 'declare(ticks=' in a PHP script (bsc#1032155).
• CVE-2016-6294: The locale_accept_from_http function in ext/intl/locale/locale_methods.c did not properly restrict calls to the ICU uloc_acceptLanguageFromHTTP function, which allowed remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a call with a long argument (bsc#1035111).

It was discovered that the PHP opcache created keys for files it cached based on their filepath. A local attacker could possibly use this issue in a shared hosting environment to obtain sensitive information. This issue only affected Ubuntu 14.04 LTS. (CVE-2015-8994)

It was discovered that the PHP URL parser incorrectly handled certain URI components. A remote attacker could possibly use this issue to bypass hostname-specific URL checks. This issue only affected Ubuntu 14.04 LTS. (CVE-2016-10397)

It was discovered that PHP incorrectly handled certain boolean parameters when unserializing data. A remote attacker could possibly use this issue to cause PHP to crash, resulting in a denial of service. This issue only affected Ubuntu 14.04 LTS. (CVE-2017-11143)

Sebastian Li, Wei Lei, Xie Xiaofei, and Liu Yang discovered that PHP incorrectly handled the OpenSSL sealing function. A remote attacker could possibly use this issue to cause PHP to crash, resulting in a denial of service. (CVE-2017-11144)

Wei Lei and Liu Yang discovered that the PHP date extension incorrectly handled memory. A remote attacker could possibly use this issue to disclose sensitive information from the server. (CVE-2017-11145)

It was discovered that PHP incorrectly handled certain PHAR archives. A remote attacker could use this issue to cause PHP to crash or disclose sensitive information. This issue only affected Ubuntu 14.04 LTS. (CVE-2017-11147)

It was discovered that PHP incorrectly handled locale length. A remote attacker could possibly use this issue to cause PHP to crash, resulting in a denial of service. (CVE-2017-11362)

Wei Lei and Liu Yang discovered that PHP incorrectly handled parsing ini files. An attacker could possibly use this issue to cause PHP to crash, resulting in a denial of service. (CVE-2017-11628)

It was discovered that PHP mbstring incorrectly handled certain regular expressions. A remote attacker could use this issue to cause PHP to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2017-9224, CVE-2017-9226, CVE-2017-9227, CVE-2017-9228, CVE-2017-9229)
