PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server.

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-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-2015-4026, 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.

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)

A double free flaw was found in zend_ts_hash_graceful_destroy() function in the PHP ZTS module. This flaw could possibly cause a PHP application to crash. (CVE-2014-9425)

All php users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, the httpd daemon must be restarted for the update to take effect.

- CVE-2015-3307 The phar_parse_metadata function in     ext/phar/phar.c in PHP before 5.4.40, 5.5.x before     5.5.24, and 5.6.x before 5.6.8 allows remote attackers     to cause a denial of service (heap metadata corruption)     or possibly have unspecified other impact via a crafted     tar archive.

  - CVE-2015-3411 + CVE-2015-3412 Fixed bug #69353 (Missing     null byte checks for paths in various PHP extensions)

  - CVE-2015-4021 The phar_parse_tarfile function in     ext/phar/tar.c in PHP before 5.4.41, 5.5.x before     5.5.25, and 5.6.x before 5.6.9 does not verify that the     first character of a filename is different from the \0     character, which allows remote attackers to cause a     denial of service (integer underflow and memory     corruption) via a crafted entry in a tar archive.

  - CVE-2015-4022 Integer overflow in the ftp_genlist     function in ext/ftp/ftp.c in PHP before 5.4.41, 5.5.x     before 5.5.25, and 5.6.x before 5.6.9 allows remote FTP     servers to execute arbitrary code via a long reply to a     LIST command, leading to a heap-based buffer overflow.

  - CVE-2015-4025 PHP before 5.4.41, 5.5.x before 5.5.25,     and 5.6.x before 5.6.9 truncates a pathname upon     encountering a \x00 character in certain situations,     which allows remote attackers to bypass intended     extension restrictions and access files or directories     with unexpected names via a crafted argument to (1)     set_include_path, (2) tempnam, (3) rmdir, or (4)     readlink. NOTE: this vulnerability exists because of an     incomplete fix for CVE-2006-7243.

  - CVE-2015-4026 The pcntl_exec implementation in PHP     before 5.4.41, 5.5.x before 5.5.25, and 5.6.x before     5.6.9 truncates a pathname upon encountering a \x00     character, which might allow remote attackers to bypass     intended extension restrictions and execute files with     unexpected names via a crafted first argument. NOTE:
    this vulnerability exists because of an incomplete fix     for CVE-2006-7243.

  - CVE-2015-4147 The SoapClient::__call method in     ext/soap/soap.c in PHP before 5.4.39, 5.5.x before     5.5.23, and 5.6.x before 5.6.7 does not verify that
    __default_headers is an array, which allows remote     attackers to execute arbitrary code by providing crafted     serialized data with an unexpected data type, related to     a 'type confusion' issue.

  - CVE-2015-4148 The do_soap_call function in     ext/soap/soap.c in PHP before 5.4.39, 5.5.x before     5.5.23, and 5.6.x before 5.6.7 does not verify that the     uri property is a string, which allows remote attackers     to obtain sensitive information by providing crafted     serialized data with an int data type, related to a     'type confusion' issue.

  - CVE-2015-4598 Incorrect handling of paths with NULs

  - CVE-2015-4599 Type confusion vulnerability in     exception::getTraceAsString

  - CVE-2015-4600 + CVE-2015-4601 Added type checks

  - CVE-2015-4602 Type Confusion Infoleak Vulnerability in     unserialize() with SoapFault

  - CVE-2015-4604 + CVE-2015-4605 denial of service when     processing a crafted file with Fileinfo (already fixed     in CVE-2015-temp-68819.patch)

  - CVE-2015-4643 Improved fix for bug #69545 (Integer     overflow in ftp_genlist() resulting in heap overflow)

  - CVE-2015-4644 Fixed bug #69667 (segfault in     php_pgsql_meta_data)

  - CVE-2015-5589 Segfault in Phar::convertToData on invalid     file

  - CVE-2015-5590 Buffer overflow and stack smashing error     in phar_fix_filepath

The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2015:1053 advisory.

    PHP is an HTML-embedded scripting language commonly used with the Apache     HTTP Server. The php55 packages provide a recent stable release of PHP with     the PEAR 1.9.4, memcache 3.0.8, and mongo 1.4.5 PECL extensions, and a     number of additional utilities.

    The php55 packages have been upgraded to upstream version 5.5.21, which     provides multiple bug fixes over the version shipped in Red Hat Software     Collections 1. (BZ#1057089)

    The following security issues were fixed in the php55-php component:

    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. (CVE-2014-8142, CVE-2015-0231, CVE-2015-0273,     CVE-2015-2787, CVE-2015-4147, CVE-2015-4148)

    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 heap buffer overflow flaw was found in PHP's regular expression     extension. An attacker able to make PHP process a specially crafted regular     expression pattern could cause it to crash and possibly execute arbitrary     code. (CVE-2015-2305)

    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)

    A use-after-free flaw was found in PHP's OPcache extension. This flaw could     possibly lead to a disclosure of a portion of the server memory.
    (CVE-2015-1351)

    A use-after-free flaw was found in PHP's phar (PHP Archive) extension.
    An attacker able to trigger certain error condition in phar archive     processing could possibly use this flaw to disclose certain portions of     server memory. (CVE-2015-2301)

    An ouf-of-bounds read flaw was found in the way the File Information     (fileinfo) extension processed certain Pascal strings. A remote attacker     could cause a PHP application to crash if it used fileinfo to identify the     type of the attacker-supplied file. (CVE-2014-9652)

    It was found that PHP move_uploaded_file() function did not properly handle     file names with 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)

    A NULL pointer dereference flaw was found in PHP's pgsql extension. A     specially crafted table name passed to a function such as pg_insert() or     pg_select() could cause a PHP application to crash. (CVE-2015-1352)

    A flaw was found in the way PHP handled malformed source files when running     in CGI mode. A specially crafted PHP file could cause PHP CGI to crash.
    (CVE-2014-9427)

    All php55 users are advised to upgrade to these updated packages, which     correct these issues. After installing the updated packages, the     httpd24-httpd service must be restarted for the update to take effect.
