(CVE-2016-4543)

  - A man-in-the-middle vulnerability exists, known as     'httpoxy', in the Apache Tomcat, Apache HTTP Server, and     PHP components due to a failure to properly resolve     namespace conflicts in accordance with RFC 3875 section     4.1.18. The HTTP_PROXY environment variable is set based     on untrusted user data in the 'Proxy' header of HTTP     requests. The HTTP_PROXY environment variable is used by     some web client libraries to specify a remote proxy     server. A remote attacker can exploit this, via a     crafted 'Proxy' header in an HTTP request, to redirect     an application's internal HTTP traffic to an arbitrary     proxy server where it may be observed or manipulated.
    (CVE-2016-5385, CVE-2016-5387, CVE-2016-5388)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

According to its banner, the version of PHP running on the remote web server is 7.0.x prior to 7.0.5. It is, therefore, affected by multiple vulnerabilities :

  - A buffer over-write condition exists in the finfo_open()     function due to improper validation of magic files. An     unauthenticated, remote attacker can exploit this, via a     crafted file, to cause a denial of service or to execute     arbitrary code.

  - A flaw exists in the php_snmp_error() function within     file ext/snmp/snmp.c that is triggered when handling     format string specifiers. An unauthenticated, remote     attacker can exploit this, via a crafted SNMP object,     to cause a denial of service or to execute arbitrary     code.

  - An invalid memory write error exists when handling     the path of phar file names that allows an attacker     to have an unspecified impact.

  - A flaw exists in the mbfl_strcut() function within file     ext/mbstring/libmbfl/mbfl/mbfilter.c when handling     negative parameter values. An unauthenticated, remote     attacker can exploit this to cause a denial of service.

  - An integer overflow condition exists in the     php_raw_url_encode() function within file     ext/standard/url.c due to improper validation of     user-supplied input. An unauthenticated, remote attacker     can exploit this to have an unspecified impact.

The remote host is affected by the vulnerability described in GLSA-201611-22 (PHP: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in PHP. Please review the       CVE identifiers referenced below for details.
  Impact :

    An attacker can possibly execute arbitrary code or create a Denial of       Service condition.
  Workaround :

    There is no known workaround at this time.

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

  - A use-after-free in onig_new_deluxe() in regext.c in     Oniguruma 6.9.2 allows attackers to potentially cause     information disclosure, denial of service, or possibly     code execution by providing a crafted regular     expression. The attacker provides a pair of a regex     pattern and a string, with a multi-byte encoding that     gets handled by onig_new_deluxe(). Oniguruma issues     often affect Ruby, as well as common optional libraries     for PHP and Rust.(CVE-2019-13224)

  - PHP 7.1.5 has an Out of bounds access in     php_pcre_replace_impl via a crafted preg_replace     call.(CVE-2017-9118)

  - Double free vulnerability in the php_wddx_process_data     function in wddx.c in the WDDX extension in PHP before     5.5.37, 5.6.x before 5.6.23, and 7.x before 7.0.8     allows remote attackers to cause a denial of service     (application crash) or possibly execute arbitrary code     via crafted XML data that is mishandled in a     wddx_deserialize call.(CVE-2016-5772)

  - When using fgetss() function to read data with     stripping tags, in PHP versions 7.2.x below 7.2.27,     7.3.x below 7.3.14 and 7.4.x below 7.4.2 it is possible     to supply data that will cause this function to read     past the allocated buffer. This may lead to information     disclosure or crash.(CVE-2020-7059)

  - When using certain mbstring functions to convert     multibyte encodings, in PHP versions 7.2.x below     7.2.27, 7.3.x below 7.3.14 and 7.4.x below 7.4.2 it is     possible to supply data that will cause function     mbfl_filt_conv_big5_wchar to read past the allocated     buffer. This may lead to information disclosure or     crash.(CVE-2020-7060)

  - In PHP versions 7.2.x below 7.2.28, 7.3.x below 7.3.15     and 7.4.x below 7.4.3, when using file upload     functionality, if upload progress tracking is enabled,     but session.upload_progress.cleanup is set to 0     (disabled), and the file upload fails, the upload     procedure would try to clean up data that does not     exist and encounter null pointer dereference, which     would likely lead to a crash.(CVE-2020-7062)

  - In PHP versions 7.2.x below 7.2.28, 7.3.x below 7.3.15     and 7.4.x below 7.4.3, when creating PHAR archive using     PharData::buildFromIterator() function, the files are     added with default permissions (0666, or all access)     even if the original files on the filesystem were with     more restrictive permissions. This may result in files     having more lax permissions than intended when such     archive is extracted.(CVE-2020-7063)

  - Format string vulnerability in the php_snmp_error     function in ext/snmp/snmp.c in PHP before 5.5.34, 5.6.x     before 5.6.20, and 7.x before 7.0.5 allows remote     attackers to execute arbitrary code via format string     specifiers in an SNMP::get call.(CVE-2016-4071)

  - The Phar extension in PHP before 5.5.34, 5.6.x before     5.6.20, and 7.x before 7.0.5 allows remote attackers to     execute arbitrary code via a crafted filename, as     demonstrated by mishandling of \0 characters by the     phar_analyze_path function in     ext/phar/phar.c.(CVE-2016-4072)

  - Multiple integer overflows in the mbfl_strcut function     in ext/mbstring/libmbfl/mbfl/mbfilter.c in PHP before     5.5.34, 5.6.x before 5.6.20, and 7.x before 7.0.5 allow     remote attackers to cause a denial of service     (application crash) or possibly execute arbitrary code     via a crafted mb_strcut call.(CVE-2016-4073)

  - In PHP 7.x before 7.0.21 and 7.1.x before 7.1.7,     ext/intl/msgformat/msgformat_parse.c does not restrict     the locale length, which allows remote attackers to     cause a denial of service (stack-based buffer overflow     and application crash) or possibly have unspecified     other impact within International Components for     Unicode (ICU) for C/C++ via a long first argument to     the msgfmt_parse_message function.(CVE-2017-11362)

  - When processing certain files, PHP EXIF extension in     versions 7.1.x below 7.1.29, 7.2.x below 7.2.18 and     7.3.x below 7.3.5 can be caused to read past allocated     buffer in exif_process_IFD_TAG function. This may lead     to information disclosure or crash.(CVE-2019-11036)

  - Function iconv_mime_decode_headers() in PHP versions     7.1.x below 7.1.30, 7.2.x below 7.2.19 and 7.3.x below     7.3.6 may perform out-of-buffer read due to integer     overflow when parsing MIME headers. This may lead to     information disclosure or crash.(CVE-2019-11039)

  - In PHP versions 7.2.x below 7.2.31, 7.3.x below 7.3.18     and 7.4.x below 7.4.6, when HTTP file uploads are     allowed, supplying overly long filenames or field names     could lead PHP engine to try to allocate oversized     memory storage, hit the memory limit and stop     processing the request, without cleaning up temporary     files created by upload request. This potentially could     lead to accumulation of uncleaned temporary files     exhausting the disk space on the target     server.(CVE-2019-11048)

  - In PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13     and 7.4.0, PHP DirectoryIterator class accepts     filenames with embedded \0 byte and treats them as     terminating at that byte. This could lead to security     vulnerabilities, e.g. in applications checking paths     that the code is allowed to access.(CVE-2019-11045)

  - 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)

  - 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)

  - 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)
