Integer overflow in the ftp_genlist function in ext/ftp/ftp.c in PHP before 5.4.42, 5.5.x before 5.5.26, and 5.6.x before 5.6.10 allows remote FTP servers to execute arbitrary code via a long reply to a LIST command, leading to a heap-based buffer overflow. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-4022.

The remote Redhat Enterprise Linux 5 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.

  - 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

According to its banner, the version of PHP 5.6.x running on the remote web server is prior to 5.6.10. It is, therefore, affected by multiple vulnerabilities :

  - Multiple heap buffer overflow conditions exist in the     bundled Perl-Compatible Regular Expression (PCRE)     library due to improper validation of user-supplied     input to the compile_branch() and pcre_compile2()     functions. A remote attacker can exploit these     conditions to cause a heap-based buffer overflow,     resulting in a denial of service condition or the     execution of arbitrary code. (CVE-2015-2325,     CVE-2015-2326)

  - A denial of service vulnerability exists in the bundled     SQLite component due to improper handling of quotes     in collation sequence names. A remote attacker can     exploit this to cause uninitialized memory access,     resulting in denial of service condition.
    (CVE-2015-3414)

  - A denial of service vulnerability exists in the bundled     SQLite component due to an improper implementation of     comparison operators in the sqlite3VdbeExec() function     in vdbe.c. A remote attacker can exploit this to cause     an invalid free operation, resulting in a denial of     service condition. (CVE-2015-3415)

  - A denial of service vulnerability exists in the bundled     SQLite component due to improper handling of precision     and width values during floating-point conversions in     the sqlite3VXPrintf() function in printf.c. A remote     attacker can exploit this to cause a stack-based buffer     overflow, resulting in a denial of service condition or     the execution of arbitrary code. (CVE-2015-3416)

  - A security bypass vulnerability exists due to a failure     in multiple extensions to check for NULL bytes in a path     when processing or reading a file. A remote attacker can     exploit this, by combining the '\0' character with a     safe file extension, to bypass access restrictions.
    (CVE-2015-4598)

  - An arbitrary command injection vulnerability exists due     to a flaw in the php_escape_shell_arg() function in     exec.c. A remote attacker can exploit this, via the     escapeshellarg() PHP method, to inject arbitrary     operating system commands. (CVE-2015-4642)

  - A heap buffer overflow condition exists in the     ftp_genlist() function in ftp.c. due to improper     validation of user-supplied input. A remote attacker     can exploit this to cause a denial of service condition     or the execution of arbitrary code. (CVE-2015-4643)     
  - A denial of service vulnerability exists due to a NULL     pointer dereference flaw in the build_tablename()     function in pgsql.c. An authenticated, remote attacker     can exploit this to cause an application crash.

Updated php packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

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

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.
(BZ#1212305)

* 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.
(BZ#1212299)

* 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. (BZ#1212298)

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.

The PHP project reports :

DOM and GD :

- Fixed bug #69719 (Incorrect handling of paths with NULs).

FTP :

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

Postgres :
