Off-by-one error in the phar_parse_zipfile function in ext/phar/zip.c in PHP before 5.5.30 and 5.6.x before 5.6.14 allows remote attackers to cause a denial of service (uninitialized pointer dereference and application crash) by including the / filename in a .zip PHAR archive.

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.

  - 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)

- CVE-2015-6831 Use after free vulnerability was found in     unserialize() function. We can create ZVAL and free it     via Serializable::unserialize. However the unserialize()     will still allow to use R: or r: to set references to     that already freed memory. It is possible to     use-after-free attack and execute arbitrary code     remotely.

  - CVE-2015-6832 Dangling pointer in the unserialization of     ArrayObject items.

  - CVE-2015-6833 Files extracted from archive may be placed     outside of destination directory

  - CVE-2015-6834 Use after free vulnerability was found in     unserialize() function. We can create ZVAL and free it     via Serializable::unserialize. However the unserialize()     will still allow to use R: or r: to set references to     that already freed memory. It is possible to     use-after-free attack and execute arbitrary code     remotely.

  - CVE-2015-6836 A type confusion occurs within SOAP     serialize_function_call due to an insufficient     validation of the headers field. In the SoapClient's
    __call method, the verify_soap_headers_array check is     applied only to headers retrieved from     zend_parse_parameters; problem is that a few lines     later, soap_headers could be updated or even replaced     with values from the __default_headers object fields.

  - CVE-2015-6837 The XSLTProcessor class misses a few     checks on the input from the libxslt library. The     valuePop() function call is able to return NULL pointer     and php does not check that.

  - CVE-2015-6838 The XSLTProcessor class misses a few     checks on the input from the libxslt library. The     valuePop() function call is able to return NULL pointer     and php does not check that.

  - CVE-2015-7803 A NULL pointer dereference flaw was found     in the way PHP's Phar extension parsed Phar archives. A     specially crafted archive could cause PHP to crash.

  - CVE-2015-7804 An uninitialized pointer use flaw was     found in the phar_make_dirstream() function of PHP's     Phar extension. A specially crafted phar file in the ZIP     format with a directory entry with a file name '/ZIP'     could cause a PHP application function to crash.

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

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2786-1 advisory.

    It was discovered that the PHP phar extension incorrectly handled certain files. A remote attacker could     use this issue to cause PHP to crash, resulting in a denial of service. (CVE-2015-7803, CVE-2015-7804)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

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

  - CVE-2015-7803     The phar extension could crash with a NULL pointer     dereference when processing tar archives containing     links referring to non-existing files. This could lead     to a denial of service.

  - CVE-2015-7804     The phar extension does not correctly process directory     entries found in archive files with the name '/',     leading to a denial of service and, potentially,     information disclosure.

The update for Debian stable (jessie) contains additional bug fixes from PHP upstream version 5.6.14, as described in the upstream changelog :

  - Note to users of the oldstable distribution (wheezy): PHP 5.4 has reached end-of-life on September 14th, 2015. As a result, there will be no more new upstream releases. The security support of PHP 5.4 in Debian oldstable (wheezy) will be best effort only, and you are strongly advised to upgrade to latest Debian stable release (jessie), which includes PHP 5.6.

As reported upstream, A NULL pointer dereference flaw was found in the way PHP's Phar extension parsed Phar archives. A specially crafted archive could cause PHP to crash. (CVE-2015-7803 )

A flaw was discovered in the way PHP performed object unserialization.
Specially crafted input processed by the unserialize() function could cause a PHP application to crash or, possibly, execute arbitrary code.
(CVE-2015-6834 , CVE-2015-6835 , CVE-2015-6836)

A NULL pointer dereference flaw was found in the XSLTProcessor class in PHP. An attacker could use this flaw to cause a PHP application to crash if it performed Extensible Stylesheet Language (XSL) transformations using untrusted XSLT files and allowed the use of PHP functions to be used as XSLT functions within XSL stylesheets.
(CVE-2015-6837 , CVE-2015-6838)

As reported upstream, an uninitialized pointer use flaw was found in the phar_make_dirstream() function of PHP's Phar extension. A specially crafted phar file in the ZIP format with a directory entry with a file name '/ZIP' could cause a PHP application function to crash. (CVE-2015-7804)

Versions of PHP 5.5.x prior to 5.5.30, or 5.6.x prior to 5.6.14 are vulnerable to the following issues :

  - A NULL pointer dereference flaw affects the phar_get_fp_offset() function in 'ext/phar/util.c' that is triggered when pointing to a non-existent file. This may allow a remote attacker to cause a denial of service.
 - An uninitialized pointer flaw affects the phar_make_dirstream() function in 'lext/phar/dirstream.c' that is triggered when handling a zip entry filename that is '/', which can result in a crash or potentially a data leak.

According to its banner, the version of PHP running on the remote web server is 5.6.x prior to 5.6.14. It is, therefore, affected by multiple vulnerabilities :

  - A NULL pointer dereference flaw exists in the     phar_get_fp_offset() function in ext/phar/util.c that is     triggered when pointing to a non-existent file. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition. (CVE-2015-7803)

  - An uninitialized pointer flaw exists in the     phar_make_dirstream() function in ext/phar/dirstream.c     that is triggered when handling a zip entry filename     that is a single forward slash. An unauthenticated,     remote attacker can exploit this to cause a denial of     service condition or to disclose sensitive information.
    (CVE-2015-7804)

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