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.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - php: buffer overflow in handling of long link names in tar phar archives (CVE-2016-2554)

  - php: Uninitialized read in exif_process_IFD_in_TIFF (CVE-2019-9641)

  - The ip2long function in PHP 5.1.4 and earlier may incorrectly validate an arbitrary string and return a     valid network IP address, which allows remote attackers to obtain network information and facilitate other     attacks, as demonstrated using SQL injection in the X-FORWARDED-FOR Header in index.php in MiniBB 2.0.
    NOTE: it could be argued that the ip2long behavior represents a risk for security-relevant issues in a way     that is similar to strcpy's role in buffer overflows, in which case this would be a class of     implementation bugs that would require separate CVE items for each PHP application that uses ip2long in a     security-relevant manner. (CVE-2006-4023)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

According to the versions of the php packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - PHP is an HTML-embedded scripting language. PHP     attempts to make it easy for developers to write     dynamically generated web pages. PHP also offers     built-in database integration for several commercial     and non-commercial database management systems, so     writing a database-enabled webpage with PHP is fairly     simple. The most common use of PHP coding is probably     as a replacement for CGI scripts. The php package     contains the module (often referred to as mod_php)     which adds support for the PHP language to Apache HTTP     Server. Security Fix(es):A flaw was found in HAProxy     before 2.0.6. In legacy mode, messages featuring a     transfer-encoding header missing the 'chunked' value     were not being correctly rejected. The impact was     limited but if combined with the 'http-reuse always'     setting, it could be used to help construct an HTTP     request smuggling attack against a vulnerable component     employing a lenient parser that would ignore the     content-length header as soon as it saw a     transfer-encoding one (even if not entirely valid     according to the specification).(CVE-2017-16642)In PHP     before 5.6.32, 7.x before 7.0.25, and 7.1.x before     7.1.11, an error in the date extension's     timelib_meridian handling of 'front of' and 'back of'     directives could be used by attackers able to supply     date strings to leak information from the interpreter,     related to ext/date/lib/parse_date.c out-of-bounds     reads affecting the php_parse_date function. NOTE: this     is a different issue than     CVE-2017-11145.(CVE-2017-11145)ext/standard/var_unseria     lizer.re in PHP before 5.6.26 mishandles     object-deserialization failures, which allows remote     attackers to cause a denial of service (memory     corruption) or possibly have unspecified other impact     via an unserialize call that references a partially     constructed object.(CVE-2016-10397)Double free     vulnerability in the zend_ts_hash_graceful_destroy     function in zend_ts_hash.c in the Zend Engine in PHP     through 5.5.20 and 5.6.x through 5.6.4 allows remote     attackers to cause a denial of service or possibly have     unspecified other impact via unknown     vectors.(CVE-2016-7412)Oniguruma through 6.9.3, as used     in PHP 7.3.x and other products, has a heap-based     buffer over-read in str_lower_case_match in     regexec.c.(CVE-2019-19246)When PHP EXIF extension is     parsing EXIF information from an image, e.g. via     exif_read_data() function, in PHP versions 7.2.x below     7.2.26, 7.3.x below 7.3.13 and 7.4.0 it is possible to     supply it with data what will cause it to read past the     allocated buffer. This may lead to information     disclosure or     crash.(CVE-2019-11047)main/php_open_temporary_file.c in     PHP before 5.5.28 and 5.6.x before 5.6.12 does not     ensure thread safety, which allows remote attackers to     cause a denial of service (race condition and heap     memory corruption) by leveraging an application that     performs many temporary-file     accesses.(CVE-2017-7272)When PHP EXIF extension is     parsing EXIF information from an image, e.g. via     exif_read_data() function, in PHP versions 7.2.x below     7.2.26, 7.3.x below 7.3.13 and 7.4.0 it is possible to     supply it with data what will cause it to read past the     allocated buffer. This may lead to information     disclosure or crash.(CVE-2019-11050)An issue was     discovered in Oniguruma 6.x before 6.9.4_rc2. In the     function fetch_interval_quantifier (formerly known as     fetch_range_quantifier) in regparse.c, PFETCH is called     without checking PEND. This leads to a heap-based     buffer     over-read.(CVE-2019-19204)main/streams/xp_socket.c in     PHP 7.x before 2017-03-07 misparses fsockopen calls,     such as by interpreting fsockopen('127.0.0.1:80', 443)     as if the address/port were 127.0.0.1:80:443, which is     later truncated to 127.0.0.1:80. This behavior has a     security risk if the explicitly provided port number     (i.e., 443 in this example) is hardcoded into an     application as a security policy, but the hostname     argument (i.e., 127.0.0.1:80 in this example) is     obtained from untrusted input.(CVE-2017-7189)

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.

Several issues have been discovered in PHP (recursive acronym for PHP:
Hypertext Preprocessor), a widely-used open source general-purpose scripting language that is especially suited for web development and can be embedded into HTML.

CVE-2016-7478: Zend/zend_exceptions.c in PHP allows remote attackers to cause a denial of service (infinite loop) via a crafted Exception object in serialized data, a related issue to CVE-2015-8876.

CVE-2016-7479: During the unserialization process, resizing the 'properties' hash table of a serialized object may lead to use-after-free. A remote attacker may exploit this bug to gain the ability of arbitrary code execution. Even though the property table issue only affects PHP 7 this change also prevents a wide range of other __wakeup() based attacks.

CVE-2017-7272: The fsockopen() function will use the port number which is defined in hostname instead of the port number passed to the second parameter of the function. This misbehavior may introduce another attack vector for an already known application vulnerability (e.g.
Server Side Request Forgery).

For Debian 7 'Wheezy', these problems have been fixed in version 5.4.45-0+deb7u8.

We recommend that you upgrade your php5 packages.
