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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

According to the version of the gd package installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  - 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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

According to its banner, the version of PHP running on the remote web server is 7.x prior to 7.0.0. It is, therefore, affected by the following vulnerabilities:

  - A directory traversal vulnerability in the     ZipArchive::extractTo function of ext/zip/php_zip.c     script. An unauthenticated, remote attacker can exploit     this, by sending a crafted ZIP archive with empty     directories, to disclose the contents of files located     outside of the server's restricted path. (CVE-2014-9767)

  - The openssl_random_pseudo_bytes() function in file     openssl.c does not generate sufficiently random numbers.
    This allows an attacker to more easily predict the     results, thus allowing further attacks to be carried     out. (CVE-2015-8867)

  - A denial of service (DoS) vulnerability exists in the GD     graphics library in the gdImageFillToBorder() function     within file gd.c when handling crafted images that have     an overly large negative coordinate. An unauthenticated,     remote attacker can exploit this, via a crafted image,     to crash processes linked against the library.
    (CVE-2015-8874)

  - A denial of service (DoS) vulnerability exists in     odbc_bindcols function of the ext/odbc/php_odbc.c script     due to mishandling driver behavior for SQL_WVARCHAR     columns. An unauthenticated, remote attacker can exploit     this issue, via the use of odbc_fetch_array function, to     cause the application to stop responding. (CVE-2015-8879)

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 5.6.x prior to 5.6.12. It is, therefore, affected by multiple vulnerabilities :

 - A use-after-free error exists in file spl_dllist.c due to improper sanitization of input to the unserialize() function. An attacker can exploit this, by using a specially crafted SplDoublyLinkedList object, to deference freed memory and thus execute arbitrary code.

 - A use-after-free error exists in file spl_observer.c due to improper sanitization of input to the unserialize() function. An attacker can exploit this, by using a specially crafted SplObjectStorage object, to deference freed memory and thus execute arbitrary code.

 - A use-after-free error exists in file spl_array.c due to improper sanitization of input to the unserialize() function. An attacker can exploit this, by using a specially crafted SplArrayObject object, to deference freed memory and thus execute arbitrary code.

 - A flaw exists in file zend_exceptions.c due to the improper use of the function unserialize() during recursive method calls. A remote attacker can exploit this to crash an application using PHP.

 - A flaw exists in file zend_exceptions.c due to insufficient type checking by functions unserialize() and __toString(). A remote attacker can exploit this to cause a NULL pointer deference or unexpected method execution, thus causing an application using PHP to crash.

 - A path traversal flaw exists in file phar_object.c due to improper sanitization of user-supplied input. An attacker can exploit this to write arbitrary files.

 - Multiple type confusion flaws exist in the _call() method in file php_http.c when handling calls for zend_hash_get_current_key or 'Z*'. An attacker can exploit this to disclose memory contents or crash an application using PHP.

 - A dangling pointer error exists in file spl_array.c due to improper sanitization of input to the unserialize() function. An attacker can exploit this, by using a specially crafted SplDoublyLinkedList object, to gain control over a deallocated pointer and thus execute arbitrary code.

 - A flaw exists in the file gd.c due to the improper handling of images with large negative coordinates by the imagefilltoborder() function. An attacker can exploit this to cause a stack overflow, thus crashing an application using PHP.

 - A flaw exists in the file php_odbc.c when the odbc_fetch_array() function handles columns that are defined as NVARCHAR(MAX). An attacker can exploit this to crash an application using PHP.

 - The openssl_random_pseudo_bytes() function in file openssl.c does not generate sufficiently random numbers. This allows an attacker to more easily predict the results, thus allowing further attacks to be carried out.

 - A user-after-free error exists in the unserialize() function in spl_observer.c due to improper validation of user-supplied input. A remote attacker can exploit this to dereference already freed memory, potentially resulting in the execution of arbitrary code.

 - A type confusion flaw exists in the serialize_function_call() function in soap.c due to improper validation of input passed via the header field. A remote attacker can exploit this to execute arbitrary code.

 - A use-after-free error exists in the unserialize() function in spl_dllist.c that is triggered during the deserialization of user-supplied input. A remote attacker can exploit this to dereference already freed memory, potentially resulting in the execution of arbitrary code.

 - A user-after-free error exists in the gmp_unserialize() function in gmp.c due to improper validation of user-supplied input. A remote attacker can exploit this to dereference already freed memory, potentially resulting in the execution of arbitrary code.

 - An integer truncation flaw exists in the zend_hash_compare() function in zend_hash.c that is triggered when comparing arrays. A remote attacker can exploit this to cause arrays to be improperly matched during comparison.

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

Several vulnerabilities were discovered in libgd2, a library for programmatic graphics creation and manipulation. A remote attacker can take advantage of these flaws to cause a denial-of-service against an application using the libgd2 library.

It was discovered that there was a stack consumption vulnerability in the libgd2 graphics library which allowed remote attackers to cause a denial of service via a crafted imagefilltoborder call.

For Debian 7 'Wheezy', this issue has been fixed in libgd2 version 2.0.36~rc1~dfsg-6.1+deb7u3.

We recommend that you upgrade your libgd2 packages.

Versions of PHP 5.6.x earlier than 5.6.12 are vulnerable to the following issues :

  - A flaw exists in the file 'gd.c' due to the improper handling of images with large negative coordinates by the imagefilltoborder() function. An attacker can exploit this to cause a stack overflow, thus crashing an application using PHP.
 - A flaw exists in the file 'php_odbc.c' when the odbc_fetch_array() function handles columns that are defined as NVARCHAR(MAX). An attacker can exploit this to crash an application using PHP.

According to its banner, the version of PHP running on the remote web server is 5.6.x prior to 5.6.12. It is, therefore, affected by multiple vulnerabilities :

  - A use-after-free error exists in file spl_dllist.c due     to improper sanitization of input to the unserialize()     function. An attacker can exploit this, by using a     specially crafted SplDoublyLinkedList object, to     deference freed memory and thus execute arbitrary code.

  - A use-after-free error exists in file spl_observer.c due     to improper sanitization of input to the unserialize()     function. An attacker can exploit this, by using a     specially crafted SplObjectStorage object, to deference     freed memory and thus execute arbitrary code.

  - A use-after-free error exists in file spl_array.c due     to improper sanitization of input to the unserialize()     function. An attacker can exploit this, by using a     specially crafted SplArrayObject object, to deference     freed memory and thus execute arbitrary code.

  - A flaw exists in file zend_exceptions.c due to the     improper use of the function unserialize() during     recursive method calls. A remote attacker can exploit     this to crash an application using PHP.

  - A flaw exists in file zend_exceptions.c due to     insufficient type checking by functions unserialize()     and __toString(). A remote attacker can exploit this to     cause a NULL pointer deference or unexpected method     execution, thus causing an application using PHP to     crash.

  - A path traversal flaw exists in file phar_object.c due     to improper sanitization of user-supplied input. An     attacker can exploit this to write arbitrary files.

  - Multiple type confusion flaws exist in the _call()     method in file php_http.c when handling calls for     zend_hash_get_current_key or 'Z*'. An attacker can     exploit this to disclose memory contents or crash     an application using PHP.

  - A dangling pointer error exists in file spl_array.c due     to improper sanitization of input to the unserialize()     function. An attacker can exploit this, by using a     specially crafted SplDoublyLinkedList object, to gain     control over a deallocated pointer and thus execute     arbitrary code.

  - A flaw exists in the file gd.c due to the improper     handling of images with large negative coordinates by     the imagefilltoborder() function. An attacker can     exploit this to cause a stack overflow, thus crashing     an application using PHP.

  - A flaw exists in the file php_odbc.c when the     odbc_fetch_array() function handles columns that are     defined as NVARCHAR(MAX). An attacker can exploit this     to crash an application using PHP.

  - The openssl_random_pseudo_bytes() function in file     openssl.c does not generate sufficiently random numbers.
    This allows an attacker to more easily predict the     results, thus allowing further attacks to be carried     out.

  - A user-after-free error exists in the unserialize()     function in spl_observer.c due to improper validation     of user-supplied input. A remote attacker can exploit     this to dereference already freed memory, potentially     resulting in the execution of arbitrary code.

  - A type confusion flaw exists in the     serialize_function_call() function in soap.c due to     improper validation of input passed via the header     field. A remote attacker can exploit this to execute     arbitrary code.

  - A use-after-free error exists in the unserialize()     function in spl_dllist.c that is triggered during the     deserialization of user-supplied input. A remote     attacker can exploit this to dereference already freed     memory, potentially resulting in the execution of     arbitrary code.

  - A user-after-free error exists in the gmp_unserialize()     function in gmp.c due to improper validation of     user-supplied input. A remote attacker can exploit this     to dereference already freed memory, potentially     resulting in the execution of arbitrary code.

  - An integer truncation flaw exists in the     zend_hash_compare() function in zend_hash.c that is     triggered when comparing arrays. A remote attacker can     exploit this to cause arrays to be improperly matched     during comparison.

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