CVE-2017-7272

PHP through 7.1.11 enables potential SSRF in applications that accept an fsockopen or pfsockopen hostname argument with an expectation that the port number is constrained. Because a :port syntax is recognized, fsockopen will use the port number that is specified in the hostname argument, instead of the port number in the second argument of the function.

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 php53 fixes the following issues:

• The fix for CVE-2017-7272 was reverted, as it caused regressions in the mysql server connect module. [bsc#1044976] The security fix tried to avoid a server side request forgery, and will be submitted when a better fix becomes available.
