The php_url_parse_ex function in ext/standard/url.c in PHP before 5.5.38 allows remote attackers to cause a denial of service (buffer over-read) or possibly have unspecified other impact via vectors involving the smart_str data type.

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.

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

  - php: Heap-based buffer over-read in mbstring regular expression functions (CVE-2019-9023)

  - Session fixation vulnerability in the Sessions subsystem in PHP before 5.5.2 allows remote attackers to     hijack web sessions by specifying a session ID. (CVE-2011-4718)

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

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

  - The get_icu_disp_value_src_php function in     ext/intl/locale/locale_methods.c in PHP before 5.3.29,     5.4.x before 5.4.30, and 5.5.x before 5.5.14 does not     properly restrict calls to the ICU uresbund.cpp     component, which allows remote attackers to cause a     denial of service (buffer overflow) or possibly have     unspecified other impact via a locale_get_display_name     call with a long first argument.(CVE-2014-9912)

  - Use-after-free vulnerability in the spl_ptr_heap_insert     function in ext/spl/spl_heap.c in PHP before 5.5.27 and     5.6.x before 5.6.11 allows remote attackers to execute     arbitrary code by triggering a failed     SplMinHeap::compare operation.(CVE-2015-4116)

  - A flaw was found in the way the way PHP's Phar     extension parsed Phar archives. A specially crafted     archive could cause PHP to crash or, possibly, execute     arbitrary code when opened.(CVE-2015-7803)

  - A flaw was found in the way the way PHP's Phar     extension parsed Phar archives. A specially crafted     archive could cause PHP to crash or, possibly, execute     arbitrary code when opened.(CVE-2015-7804)

  - ext/libxml/libxml.c in PHP before 5.5.22 and 5.6.x     before 5.6.6, when PHP-FPM is used, does not isolate     each thread from libxml_disable_entity_loader changes     in other threads, which allows remote attackers to     conduct XML External Entity (XXE) and XML Entity     Expansion (XEE) attacks via a crafted XML document, a     related issue to CVE-2015-5161.(CVE-2015-8866)

  - Stack consumption vulnerability in GD in PHP before     5.6.12 allows remote attackers to cause a denial of     service via a crafted imagefilltoborder     call.(CVE-2015-8874)

  - It was found that the exif_convert_any_to_int()     function in PHP was vulnerable to floating point     exceptions when parsing tags in image files. A remote     attacker with the ability to upload a malicious image     could crash PHP, causing a Denial of     Service.(CVE-2016-10158)

  - Integer overflow in the phar_parse_pharfile function in     ext/phar/phar.c in PHP before 5.6.30 and 7.0.x before     7.0.15 allows remote attackers to cause a denial of     service (memory consumption or application crash) via a     truncated manifest entry in a PHAR     archive.(CVE-2016-10159)

  - The php_url_parse_ex function in ext/standard/url.c in     PHP before 5.5.38 allows remote attackers to cause a     denial of service (buffer over-read) or possibly have     unspecified other impact via vectors involving the     smart_str data type.(CVE-2016-6288)

  - The exif_process_IFD_in_MAKERNOTE function in     ext/exif/exif.c in PHP before 5.5.38, 5.6.x before     5.6.24, and 7.x before 7.0.9 allows remote attackers to     cause a denial of service (out-of-bounds array access     and memory corruption), obtain sensitive information     from process memory, or possibly have unspecified other     impact via a crafted JPEG image.(CVE-2016-6291)

  - The exif_process_user_comment function in     ext/exif/exif.c in PHP before 5.5.38, 5.6.x before     5.6.24, and 7.x before 7.0.9 allows remote attackers to     cause a denial of service (NULL pointer dereference and     application crash) via a crafted JPEG     image.(CVE-2016-6292)

  - The locale_accept_from_http function in     ext/intl/locale/locale_methods.c in PHP before 5.5.38,     5.6.x before 5.6.24, and 7.x before 7.0.9 does not     properly restrict calls to the ICU     uloc_acceptLanguageFromHTTP function, which allows     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.(CVE-2016-6294)

  - ext/session/session.c in PHP before 5.6.25 and 7.x     before 7.0.10 skips invalid session names in a way that     triggers incorrect parsing, which allows remote     attackers to inject arbitrary-type session data by     leveraging control of a session name, as demonstrated     by object injection.(CVE-2016-7125)

  - The exif_process_IFD_in_TIFF function in     ext/exif/exif.c in PHP before 5.6.25 and 7.x before     7.0.10 mishandles the case of a thumbnail offset that     exceeds the file size, which allows remote attackers to     obtain sensitive information from process memory via a     crafted TIFF image.(CVE-2016-7128)

  - The php_wddx_push_element function in ext/wddx/wddx.c     in PHP before 5.6.26 and 7.x before 7.0.11 allows     remote attackers to cause a denial of service (invalid     pointer access and out-of-bounds read) or possibly have     unspecified other impact via an incorrect boolean     element in a wddxPacket XML document, leading to     mishandling in a wddx_deserialize call.(CVE-2016-7418)

  - In PHP before 5.6.31, 7.x before 7.0.21, and 7.1.x     before 7.1.7, a stack-based buffer overflow in the     zend_ini_do_op() function in Zend/zend_ini_parser.c     could cause a denial of service or potentially allow     executing code. NOTE: this is only relevant for PHP     applications that accept untrusted input (instead of     the system's php.ini file) for the parse_ini_string or     parse_ini_file function, e.g., a web application for     syntax validation of php.ini     directives.(CVE-2017-11628)

  - An issue was discovered in PHP before 5.6.35, 7.0.x     before 7.0.29, 7.1.x before 7.1.16, and 7.2.x before     7.2.4. Dumpable FPM child processes allow bypassing     opcache access controls because fpm_unix.c makes a     PR_SET_DUMPABLE prctl call, allowing one user (in a     multiuser environment) to obtain sensitive information     from the process memory of a second user's PHP     applications by running gcore on the PID of the PHP-FPM     worker process.(CVE-2018-10545)

  - An issue was discovered in ext/phar/phar_object.c in     PHP before 5.6.36, 7.0.x before 7.0.30, 7.1.x before     7.1.17, and 7.2.x before 7.2.5. There is Reflected XSS     on the PHAR 403 and 404 error pages via request data of     a request for a .phar file.(CVE-2018-10547)

  - exif_process_IFD_in_MAKERNOTE in ext/exif/exif.c in PHP     before 5.6.37, 7.0.x before 7.0.31, 7.1.x before     7.1.20, and 7.2.x before 7.2.8 allows remote attackers     to cause a denial of service (out-of-bounds read and     application crash) via a crafted JPEG     file.(CVE-2018-14851)

  - A cross-site scripting (XSS) vulnerability in Apache2     component of PHP was found. When using     'Transfer-Encoding: chunked', the request allows remote     attackers to potentially run a malicious script in a     victim's browser. This vulnerability can be exploited     only by producing malformed requests and it's believed     it's unlikely to be used in practical cross-site     scripting attack.(CVE-2018-17082)

  - gd_gif_in.c in the GD Graphics Library (aka libgd), as     used in PHP before 5.6.33, 7.0.x before 7.0.27, 7.1.x     before 7.1.13, and 7.2.x before 7.2.1, has an integer     signedness error that leads to an infinite loop via a     crafted GIF file, as demonstrated by a call to the     imagecreatefromgif or imagecreatefromstring PHP     function. This is related to GetCode_ and     gdImageCreateFromGifCtx.(CVE-2018-5711)

  - An issue was discovered in PHP before 5.6.33, 7.0.x     before 7.0.27, 7.1.x before 7.1.13, and 7.2.x before     7.2.1. There is Reflected XSS on the PHAR 404 error     page via the URI of a request for a .phar     file.(CVE-2018-5712)

Versions of PHP 5.5.x prior to 5.5.38, or 5.6.x prior to 5.6.24, or 7.0.x prior to 7.0.9 are vulnerable to the following issues :

 - A NULL pointer dereference flaw within the '_gdScaleVert()' function inside of 'ext/gd/libgd/gd_interpolation.c' is triggered during the handling of '_gdContributionsCalc' return values. This may allow a remote attacker to cause a denial of service in a process linked against PHP.
 - A flaw related to missing protection against 'RFC 3875 section 4.1.18' namespace conflicts is triggered when handling requests containing 'Proxy' HTTP headers. These may be stored in the 'HTTP_PROXY' environment variable also commonly used to configure an outbound HTTP proxy for applications. With a specially crafted request, a remote attacker can specify an arbitrary HTTP proxy server to be used by applications relying on the HTTP_PROXY environment variable. (CVE-2016-5385)
 - An out-of-bounds read flaw within the 'gdImageScaleBilinearPalette()' function inside of 'gd_interpolation.c' is triggered when handling transparent colors. This may allow a context-dependent attacker to crash a process linked against the library or potentially disclose memory contents.
 - A flaw within the 'gdImageScaleTwoPass()' function inside of 'gd_interpolation.c' is triggered as certain input is not properly validated. This may allow a context-dependent attacker to crash a process linked against the library. (CVE-2016-6207)
 - A use-after-free error within 'ext/snmp/snmp.c' is triggered during the unserialization of user-supplied input when handling garbage collection. This may allow a remote attacker to dereference already freed memory and potentially execute arbitrary code. (CVE-2016-6295)
 - An out-of-bounds read flaw within the 'uloc_acceptLanguageFromHTTP()' function inside of 'common/uloc.cpp' may allow a remote attacker to crash a program using the language or potentially disclose memory contents. (CVE-2016-6293, CVE-2016-6294)
 - A use-after-free error within 'ext/session/session.c' is triggered during the handling of 'var_hash destruction'. This may allow a remote attacker to dereference already freed memory and potentially execute arbitrary code. (CVE-2016-6290)
 - An out-of-bounds read flaw within the 'exif_process_IFD_in_MAKERNOTE()' function inside of 'ext/exif/exif.c' may allow a remote attacker to crash a program using the language or potentially disclose memory contents. (CVE-2016-6291)
 - An overflow condition within the 'php_bz2iop_read()' function inside of 'ext/bz2/bz2.c' is triggered as error conditions are not properly handled. With a specially crafted request, a remote attacker can cause a buffer overflow and potentially execute arbitrary code. (CVE-2016-5399)
 - An overflow condition within the 'mdecrypt_generic()' function inside of 'ext/mcrypt/mcrypt.c' is triggered as user-supplied input is not properly validated. This may allow a remote attacker to cause a heap-based buffer overflow, crashing a program using the language or potentially allowing the execution of arbitrary code.
 - A NULL pointer dereference flaw within the 'exif_process_user_comment()' function inside of 'ext/exif/exif.c' may allow a remote attacker to crash a program using the language. (CVE-2016-6292)
 - A flaw within the 'curl_unescape()' function inside of 'ext/curl/interface.c' is triggered during the handling of string lengths. This may allow a remote attacker to trigger heap corruption and crash a program using the language.
 - An overflow condition within the 'mcrypt_generic()' function inside of 'ext/mcrypt/mcrypt.c' is triggered as user-supplied input is not properly validated. This may allow a remote attacker to cause a heap-based buffer overflow, resulting in a denial of service or potentially allowing the execution of arbitrary code.
 - An integer overflow condition within the 'php_stream_zip_opener()' function inside of 'ext/zip/zip_stream.c' is triggered as user-supplied input is not properly validated when handling zip streams. This may allow a remote attacker to cause a stack-based buffer overflow, crashing a program using the language or potentially allowing the execution of arbitrary code. (CVE-2016-6297)
 - An integer overflow condition within the 'virtual_file_ex()' function inside of 'Zend/zend_virtual_cwd.c' is triggered as user-supplied input is not properly validated when handling variables. This may allow a remote attacker to cause a stack-based buffer overflow, crashing a program using the language or potentially allowing the execution of arbitrary code. (CVE-2016-6289)
 - An overflow condition within the 'simplestring_addn()' function inside of 'simplestring.c.' is triggered as user-supplied input is not properly validated. This may allow a context-dependent attacker to cause a heap-based buffer overflow, resulting in a denial of service in a process linked against the library or potentially allowing the execution of arbitrary code. (CVE-2016-6296)
 - A NULL write flaw within the 'gdImageColorTransparent()' function inside of 'gd.c' is triggered during the handling of negative transparent colors. This may allow a context-dependent attacker to disclose memory.
 - An overflow condition within the 'php_url_prase_ex()' function inside of 'ext/standard/url.c' is triggered as user-supplied input is not properly validated. This may allow a remote attacker to cause a buffer overflow, potentially resulting in a denial of service in a process utilizing the language. (CVE-2016-6288)

According to its banner, the version of PHP running on the remote web server is 5.5.x prior to 5.5.38. It is, therefore, affected by multiple vulnerabilities :

  - A Segfault condition occurs when accessing     nvarchar(max) defined columns. (CVE-2015-8879)

  - A man-in-the-middle vulnerability exists, known as     'httpoxy', 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. An unauthenticated, 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)

  - An overflow condition exists in the php_bz2iop_read()     function within file ext/bz2/bz2.c due to improper     handling of error conditions. An unauthenticated, remote     attacker can exploit this, via a crafted request, to     execute arbitrary code. (CVE-2016-5399)

  - A flaw exists in the GD Graphics Library (libgd),     specifically in the gdImageScaleTwoPass() function     within file gd_interpolation.c, due to improper     validation of user-supplied input. An unauthenticated,     remote attacker can exploit this to cause a denial of     service condition. (CVE-2016-6207)

  - A buffer overflow condition exists in the     php_url_parse_ex() function. (CVE-2016-6288)

  - An integer overflow condition exists in the     virtual_file_ex() function within file     Zend/zend_virtual_cwd.c due to improper validation of     user-supplied input. An unauthenticated, remote attacker     can exploit this to cause a denial of service condition     or the execution of arbitrary code. (CVE-2016-6289)

  - A use-after-free error exists within the file     ext/session/session.c when handling 'var_hash'     destruction. An unauthenticated, remote attacker can     exploit this to deference already freed memory,     resulting in the execution of arbitrary code.
    (CVE-2016-6290)

  - An out-of-bounds read error exists in the     exif_process_IFD_in_MAKERNOTE() function within file     ext/exif/exif.c. An unauthenticated, remote attacker can     exploit this to cause a denial of service condition or     disclose memory contents. (CVE-2016-6291)

  - A NULL pointer dereference flaw exists in the     exif_process_user_comment() function within file     ext/exif/exif.c. An unauthenticated, remote attacker can     exploit this to cause a denial of service condition.
    (CVE-2016-6292)

  - Multiple out-of-bounds read errors exist in the     locale_accept_from_http() function within file     ext/intl/locale/locale_methods.c. An unauthenticated,     remote attacker can exploit these to cause a denial of     service condition or disclose memory contents.
    (CVE-2016-6293, CVE-2016-6294)

  - A use-after-free error exists within file     ext/snmp/snmp.c when handling garbage collection during     deserialization of user-supplied input. An     unauthenticated, remote attacker can exploit this to     deference already freed memory, resulting in the     execution of arbitrary code. (CVE-2016-6295)

  - A heap-based buffer overflow condition exists in the     simplestring_addn() function within file simplestring.c     due to improper validation of user-supplied input. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition or the execution of     arbitrary code. (CVE-2016-6296)

  - An integer overflow condition exists in the     php_stream_zip_opener() function within file     ext/zip/zip_stream.c due to improper validation of     user-supplied input when handling zip streams. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition or the execution of     arbitrary code. (CVE-2016-6297)

  - An out-of-bounds read error exists in the GD Graphics     Library (libgd), specifically in the     gdImageScaleBilinearPalette() function within file     gd_interpolation.c, when handling transparent color. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition or disclose     memory contents.

  - A heap-based buffer overflow condition exists in the     mdecrypt_generic() function within file     ext/mcrypt/mcrypt.c due to improper validation of     user-supplied input. An unauthenticated, remote attacker     can exploit this to cause a denial of service condition     or the execution of arbitrary code.

  - A NULL write flaw exists in the GD Graphics Library     (libgd) in the gdImageColorTransparent() function due to     improper handling of negative transparent colors. A     remote attacker can exploit this to disclose memory     contents.

  - An overflow condition exists in the php_url_prase_ex()     function due to improper validation of user-supplied     input. A remote attacker can exploit this to cause a     buffer overflow, resulting in a denial of service     condition.
