ext/snmp/snmp.c in PHP before 5.5.38, 5.6.x before 5.6.24, and 7.x before 7.0.9 improperly interacts with the unserialize implementation and garbage collection, which allows remote attackers to cause a denial of service (use-after-free and application crash) or possibly have unspecified other impact via crafted serialized data, a related issue to CVE-2016-5773.

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.

This plugin has been deprecated as it does not adhere to established standards for this style of check.

According to its banner, the version of PHP running on the remote web server is 7.0.x prior to 7.0.9. It is, therefore, affected by multiple vulnerabilities :

 - 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)

 - 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 flaw exists in the curl_unescape() function within file ext/curl/interface.c when handling string lengths. An unauthenticated, remote attacker can exploit this to cause heap corruption, resulting in a denial of service condition.

 - A heap-based buffer overflow condition exists in the mcrypt_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.

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

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

  - Zend/zend_exceptions.c in PHP, possibly 5.x before     5.6.28 and 7.x before 7.0.13, 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-2016-7478)

  - ext/spl/spl_array.c in PHP before 5.6.26 and 7.x before     7.0.11 proceeds with SplArray unserialization without     validating a return value and data type, which allows     remote attackers to cause a denial of service or     possibly have unspecified other impact via crafted     serialized data.(CVE-2016-7417)

  - ext/phar/phar_object.c in PHP before 5.5.32, 5.6.x     before 5.6.18, and 7.x before 7.0.3 mishandles     zero-length uncompressed data, which allows remote     attackers to cause a denial of service (heap memory     corruption) or possibly have unspecified other impact     via a crafted (1) TAR, (2) ZIP, or (3) PHAR     archive.(CVE-2016-4342)

  - The php_wddx_process_data function in ext/wddx/wddx.c     in PHP before 5.6.25 and 7.x before 7.0.10 allows     remote attackers to cause a denial of service     (segmentation fault) or possibly have unspecified other     impact via an invalid ISO 8601 time value, as     demonstrated by a wddx_deserialize call that mishandles     a dateTime element in a wddxPacket XML     documenti1/4Z(CVE-2016-7129)

  - Integer signedness error in the simplestring_addn     function in simplestring.c in xmlrpc-epi through     0.54.2, as used 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 (heap-based buffer     overflow) or possibly have unspecified other impact via     a long first argument to the PHP xmlrpc_encode_request     function.(CVE-2016-6296)

  - ext/snmp/snmp.c in PHP before 5.5.38, 5.6.x before     5.6.24, and 7.x before 7.0.9 improperly interacts with     the unserialize implementation and garbage collection,     which allows remote attackers to cause a denial of     service (use-after-free and application crash) or     possibly have unspecified other impact via crafted     serialized data, a related issue to     CVE-2016-5773.(CVE-2016-6295)

  - ext/session/session.c in PHP before 5.5.38, 5.6.x     before 5.6.24, and 7.x before 7.0.9 does not properly     maintain a certain hash data structure, which allows     remote attackers to cause a denial of service     (use-after-free) or possibly have unspecified other     impact via vectors related to session     deserialization.(CVE-2016-6290)

  - Integer overflow in the php_stream_zip_opener function     in ext/zip/zip_stream.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 (stack-based     buffer overflow) or possibly have unspecified other     impact via a crafted zip:// URL.(CVE-2016-6297)

  - The phar_make_dirstream function in     ext/phar/dirstream.c in PHP before 5.6.18 and 7.x     before 7.0.3 mishandles zero-size ././@LongLink files,     which allows remote attackers to cause a denial of     service (uninitialized pointer dereference) or possibly     have unspecified other impact via a crafted TAR     archive.(CVE-2016-4343)

  - ext/intl/msgformat/msgformat_format.c in PHP before     5.6.26 and 7.x before 7.0.11 does not properly restrict     the locale length provided to the Locale class in the     ICU library, which allows remote attackers to cause a     denial of service (application crash) or possibly have     unspecified other impact via a     MessageFormatter::formatMessage call with a long first     argument.(CVE-2016-7416)

  - ext/wddx/wddx.c in PHP before 5.6.25 and 7.x before     7.0.10 allows remote attackers to cause a denial of     service (NULL pointer dereference and application     crash) or possibly have unspecified other impact via a     malformed wddxPacket XML document that is mishandled in     a wddx_deserialize call, as demonstrated by a tag that     lacks a i1/4oe (less than) character.(CVE-2016-7131)

  - ext/wddx/wddx.c in PHP before 5.6.25 and 7.x before     7.0.10 allows remote attackers to cause a denial of     service (NULL pointer dereference and application     crash) or possibly have unspecified other impact via an     invalid wddxPacket XML document that is mishandled in a     wddx_deserialize call, as demonstrated by a stray     element inside a boolean element, leading to incorrect     pop processing.(CVE-2016-7132)

  - The php_wddx_pop_element function in ext/wddx/wddx.c in     PHP before 5.6.25 and 7.x before 7.0.10 allows remote     attackers to cause a denial of service (NULL pointer     dereference and application crash) or possibly have     unspecified other impact via an invalid base64 binary     value, as demonstrated by a wddx_deserialize call that     mishandles a binary element in a wddxPacket XML     documenti1/4Z( CVE-2016-7130)

  - The imagegammacorrect function in ext/gd/gd.c in PHP     before 5.6.25 and 7.x before 7.0.10 does not properly     validate gamma values, which allows remote attackers to     cause a denial of service (out-of-bounds write) or     possibly have unspecified other impact by providing     different signs for the second and third     arguments.(CVE-2016-7127)

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)

Several vulnerabilities were found in PHP, a general-purpose scripting language commonly used for web application development.

The vulnerabilities are addressed by upgrading PHP to the new upstream version 5.6.24, which includes additional bug fixes. Please refer to the upstream changelog for more information :

According to its banner, the version of PHP running on the remote web server is 7.0.x prior to 7.0.9. It is, therefore, affected by multiple vulnerabilities :

  - 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)

According to its banner, the version of PHP running on the remote web server is 5.6.x prior to 5.6.24. It is, therefore, affected by multiple vulnerabilities :

  - 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)
