The mcopy function in softmagic.c in file 5.x, as used in the Fileinfo component in PHP before 5.4.40, 5.5.x before 5.5.24, and 5.6.x before 5.6.8, does not properly restrict a certain offset value, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted string that is mishandled by a "Python script text executable" rule.

The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2015:1066 advisory.

    PHP is an HTML-embedded scripting language commonly used with the Apache     HTTP Server. The php54 packages provide a recent stable release of PHP with     the PEAR 1.9.4, APC 3.1.15, and memcache 3.0.8 PECL extensions, and a     number of additional utilities.

    The php54 packages have been upgraded to upstream version 5.4.40, which     provides a number of bug fixes over the version shipped in Red Hat Software     Collections 1. (BZ#1168193)

    The following security issues were fixed in the php54-php component:

    A flaw was found in the way the PHP module for the Apache httpd web server     handled pipelined requests. A remote attacker could use this flaw to     trigger the execution of a PHP script in a deinitialized interpreter,     causing it to crash or, possibly, execute arbitrary code. (CVE-2015-3330)

    An uninitialized pointer use flaw was found in PHP's Exif extension. A     specially crafted JPEG or TIFF file could cause a PHP application using the     exif_read_data() function to crash or, possibly, execute arbitrary code     with the privileges of the user running that PHP application.
    (CVE-2015-0232)

    Multiple flaws were 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.

A flaw was found in the way the PHP module for the Apache httpd web server handled pipelined requests. A remote attacker could use this flaw to trigger the execution of a PHP script in a deinitialized interpreter, causing it to crash or, possibly, execute arbitrary code.
(CVE-2015-3330)

A flaw was found in the way PHP parsed multipart HTTP POST requests. A specially crafted request could cause PHP to use an excessive amount of CPU time. (CVE-2015-4024)

An uninitialized pointer use flaw was found in PHP's Exif extension. A specially crafted JPEG or TIFF file could cause a PHP application using the exif_read_data() function to crash or, possibly, execute arbitrary code with the privileges of the user running that PHP application. (CVE-2015-0232)

An integer overflow flaw leading to a heap-based buffer overflow was found in the way PHP's FTP extension parsed file listing FTP server responses. A malicious FTP server could use this flaw to cause a PHP application to crash or, possibly, execute arbitrary code.
(CVE-2015-4022)

Multiple flaws were 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-2014-8142, CVE-2015-0231, CVE-2015-0273, CVE-2015-2787, CVE-2015-4147, CVE-2015-4148, CVE-2015-4599, CVE-2015-4600, CVE-2015-4601, CVE-2015-4602, CVE-2015-4603)

It was found that certain PHP functions did not properly handle file names containing a NULL character. A remote attacker could possibly use this flaw to make a PHP script access unexpected files and bypass intended file system access restrictions. (CVE-2015-2348, CVE-2015-4025, CVE-2015-4026, CVE-2015-3411, CVE-2015-3412, CVE-2015-4598)

Multiple flaws were 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-2015-2301, CVE-2015-2783, CVE-2015-3307, CVE-2015-3329, CVE-2015-4021)

Multiple flaws were found in PHP's File Information (fileinfo) extension. A remote attacker could cause a PHP application to crash if it used fileinfo to identify type of attacker supplied files.
(CVE-2014-9652, CVE-2015-4604, CVE-2015-4605)

A heap buffer overflow flaw was found in the enchant_broker_request_dict() function of PHP's enchant extension. An attacker able to make a PHP application enchant dictionaries could possibly cause it to crash. (CVE-2014-9705)

A buffer over-read flaw was found in the GD library used by the PHP gd extension. A specially crafted GIF file could cause a PHP application using the imagecreatefromgif() function to crash. (CVE-2014-9709)

This update also fixes the following bugs :

  - The libgmp library in some cases terminated unexpectedly     with a segmentation fault when being used with other     libraries that use the GMP memory management. With this     update, PHP no longer changes libgmp memory allocators,     which prevents the described crash from occurring.

  - When using the Open Database Connectivity (ODBC) API,     the PHP process in some cases terminated unexpectedly     with a segmentation fault. The underlying code has been     adjusted to prevent this crash.

  - Previously, running PHP on a big-endian system sometimes     led to memory corruption in the fileinfo module. This     update adjusts the behavior of the PHP pointer so that     it can be freed without causing memory corruption.

After installing the updated packages, the httpd daemon must be restarted for the update to take effect.

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

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

Versions of PHP 5.4.x earlier than 5.4.40, 5.5.x earlier than 5.5.24, or 5.6.x earlier than 5.6.8 are exposed to the following issues :

  - An out-of-bounds read overflow error exists in the function 'GetCode_()' in file 'gd_gif_in.c' that allows denial of service attacks or disclosure of memory contents. (CVE-2014-9709)
  - A use-after-free error exists in the OPcache extension in the '_zend_shared_memdup()' function within the file 'zend_shared_alloc.c'. A remote attacker can exploit this to cause a denial of service or possibly have other unspecified impact. (CVE-2015-1351)
  - The function 'build_tablename()' in file 'pgsql.c' in the PostgreSQL extension does not properly validate token extraction for table names. A remote attacker, using a crafted name, can exploit this to cause a NULL pointer deference, leading to a denial of service. (CVE-2015-1352)
  - A use-after-free error exists in the function 'phar_rename_archive()' in file 'phar_object.c'. A remote attacker, by attempting to rename a phar archive to an already existing file name, can exploit this to cause a denial of service. (CVE-2015-2301)
  - A buffer read overflow error exists in the Phar component due to user-supplied input not being validated properly when handling phar parsing during 'unserialize()' function calls. An attacker can exploit this to execute arbitrary code or cause a denial of service. (CVE-2015-2783)
  - A buffer overflow flaw exists in the 'phar_set_inode()' function in file 'phar_internal.h' when handling archive files, such as tar, zip, or phar files. A remote attacker can exploit this to execute arbitrary code or cause a denial of service. (CVE-2015-3329)
  - A flaw exists in the Apache2handler SAPI component, when handling pipelined HTTP requests, that a remote attacker can exploit to execute arbitrary code. (CVE-2015-3330)
  - An information disclosure vulnerability exists because of a type confusion error. Specifically, this issue occurs when the 'unserialize()' function is used with SoapFault object's '__toString()' function. An attacker can exploit this issue to leak arbitrary memory blocks.
  - A flaw exists in the 'phar_parse_metadata()' function in 'ext/phar/phar.c'. The issue is triggered as user-supplied input is not properly validated when parsing a specially crafted TAR file. This may allow a remote attacker to corrupt memory and cause a denial of service or potentially execute arbitrary code. (CVE-2015-3307)
  - A type confusion flaw exists in the '__toString()' method in 'incomplete_class.c' that may allow a context-dependent attacker to leak arbitrary memory blocks or potentially cause a denial of service. (CVE-2015-4602)
  - Multiple unspecified issues exist in '/soap/php_http.c' and '/soap/php_encoding.c'. This may allow an attacker to have an unspecified impact. (CVE-2015-4601)
  - A denial of service vulnerability affects Fine Free File, a common component used in PHP known as 'file'. Specifically, this issue affects the source file 'libmagic/softmagic.c' because it fails to properly handle offsets that exceed 'bytecnt' or vice versa. (CVE-2015-4605)

According to its banner, the version of PHP 5.6.x running on the remote web server is prior to 5.6.8. It is, therefore, affected by multiple vulnerabilities :

  - An out-of-bounds read error exists in the Phar component     due to improper validation of user-supplied input when     handling phar parsing during unserialize() function     calls. An unauthenticated, remote attacker can exploit     this to cause a denial of service condition or the     disclosure of memory contents. (CVE-2015-2783)

  - A memory corruption issue exists in the     phar_parse_metadata() function in file ext/phar/phar.c     due to improper validation of user-supplied input when     parsing a specially crafted TAR archive. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition or the execution of     arbitrary code. (CVE-2015-3307)

  - Multiple stack-based buffer overflow conditions exist in     the phar_set_inode() function in file phar_internal.h     when handling archive files, such as tar, zip, or phar     files. An unauthenticated, remote attacker can exploit     these to cause a denial of service condition or the     execution or arbitrary code. (CVE-2015-3329)

  - A flaw exists in the Apache2handler SAPI component when     handling pipelined HTTP requests that allows an     unauthenticated, remote attacker to cause a denial of     service condition or the execution of arbitrary code.
    (CVE-2015-3330)

  - A flaw exists in multiple functions due to a failure to     check for NULL byte (%00) sequences in a path when     processing or reading a file. An unauthenticated, remote     attacker can exploit this, via specially crafted input     to an application calling those functions, to bypass     intended restrictions and disclose potentially     sensitive information. (CVE-2015-3411, CVE-2015-3412)

  - A type confusion error exists in multiple functions     within file ext/soap/soap.c that is triggered when     calling unserialize(). An unauthenticated, remote     attacker can exploit this to disclose memory contents,     cause a denial of service condition, or execute     arbitrary code. (CVE-2015-4599, CVE-2015-4600)

  - Multiple type confusion errors exist within files     ext/soap/php_encoding.c, ext/soap/php_http.c, and     ext/soap/soap.c that allow an unauthenticated, remote     attacker to cause a denial of service condition or the     execution of arbitrary code. (CVE-2015-4601)

  - A type confusion error exists in the
    __PHP_Incomplete_Class() function within file     ext/standard/incomplete_class.c that allows an     unauthenticated, remote attacker to cause a denial of     service condition or the execution of arbitrary code.
    (CVE-2015-4602)

  - A type confusion error exists in the     exception::getTraceAsString() function within file     Zend/zend_exceptions.c that allows a remote attacker to     execute arbitrary code. (CVE-2015-4603)

  - A denial of service vulnerability exists due to a flaw     in the bundled libmagic library, specifically in the     mget() function within file softmagic.c. The function     fails to maintain a certain pointer relationship. An     unauthenticated, remote attacker can exploit this, via a     crafted string, to crash the application.
    (CVE-2015-4604)

  - A denial of service vulnerability exists due to a flaw     in the bundled libmagic library, specifically in the     mcopy() function within file softmagic.c. The function     fails to properly handle an offset that exceeds     'bytecnt'. An unauthenticated, remote attacker can     exploit this, via a crafted string, to crash the     application. (CVE-2015-4605)

  - A use-after-free error exists in the sqlite3_close()     function within file /ext/sqlite3/sqlite3.c when closing     database connections. An unauthenticated, remote     attacker can exploit this to execute arbitrary code.

  - A type confusion error exists in the     php_stream_url_wrap_http_ex() function within file     ext/standard/http_fopen_wrapper.c that allows an     unauthenticated, remote attacker to execute arbitrary     code.

  - A use-after-free error exists in the php_curl() function     within file ext/curl/interface.c that allows an     unauthenticated, remote attacker to execute arbitrary     code.

  - A NULL pointer dereference flaw exists within file     /ext/ereg/regex/regcomp.c that allows an     unauthenticated, remote attacker attacker to cause a     denial of service condition.

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