sapi/fpm/fpm/fpm_unix.c in the FastCGI Process Manager (FPM) in PHP before 5.4.28 and 5.5.x before 5.5.12 uses 0666 permissions for the UNIX socket, which allows local users to gain privileges via a crafted FastCGI client.

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.

  - 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.

froxlor was updated to version 0.9.34 (bnc#846355), fixing bugs and bringing features.

Multiple vulnerabilities has been discovered and corrected in php :

It was discovered that the file utility contains a flaw in the handling of indirect magic rules in the libmagic library, which leads to an infinite recursion when trying to determine the file type of certain files (CVE-2014-1943).

A flaw was found in the way the file utility determined the type of Portable Executable (PE) format files, the executable format used on Windows. A malicious PE file could cause the file utility to crash or, potentially, execute arbitrary code (CVE-2014-2270).

The BEGIN regular expression in the awk script detector in magic/Magdir/commands in file before 5.15 uses multiple wildcards with unlimited repetitions, which allows context-dependent attackers to cause a denial of service (CPU consumption) via a crafted ASCII file that triggers a large amount of backtracking, as demonstrated via a file with many newline characters (CVE-2013-7345).

PHP FPM in PHP versions before 5.4.28 and 5.5.12 uses a UNIX domain socket with world-writable permissions by default, which allows any local user to connect to it and execute PHP scripts as the apache user (CVE-2014-0185).

A flaw was found in the way file's Composite Document Files (CDF) format parser handle CDF files with many summary info entries. The cdf_unpack_summary_info() function unnecessarily repeatedly read the info from the same offset. This led to many file_printf() calls in cdf_file_property_info(), which caused file to use an excessive amount of CPU time when parsing a specially crafted CDF file (CVE-2014-0237).

A flaw was found in the way file parsed property information from Composite Document Files (CDF) files. A property entry with 0 elements triggers an infinite loop (CVE-2014-0238).

The unserialize() function in PHP before 5.4.30 and 5.5.14 has a Type Confusion issue related to the SPL ArrayObject and SPLObjectStorage Types (CVE-2014-3515).

It was discovered that PHP is vulnerable to a heap-based buffer overflow in the DNS TXT record parsing. A malicious server or man-in-the-middle attacker could possibly use this flaw to execute arbitrary code as the PHP interpreter if a PHP application uses dns_get_record() to perform a DNS query (CVE-2014-4049).

A flaw was found in the way file parsed property information from Composite Document Files (CDF) files, where the mconvert() function did not correctly compute the truncated pascal string size (CVE-2014-3478).

Multiple flaws were found in the way file parsed property information from Composite Document Files (CDF) files, due to insufficient boundary checks on buffers (CVE-2014-0207, CVE-2014-3479, CVE-2014-3480, CVE-2014-3487).

The phpinfo() function in PHP before 5.4.30 and 5.5.14 has a Type Confusion issue that can cause it to leak arbitrary process memory (CVE-2014-4721).

Use-after-free vulnerability in ext/spl/spl_array.c in the SPL component in PHP through 5.5.14 allows context-dependent attackers to cause a denial of service or possibly have unspecified other impact via crafted ArrayIterator usage within applications in certain web-hosting environments (CVE-2014-4698).

Use-after-free vulnerability in ext/spl/spl_dllist.c in the SPL component in PHP through 5.5.14 allows context-dependent attackers to cause a denial of service or possibly have unspecified other impact via crafted iterator usage within applications in certain web-hosting environments (CVE-2014-4670).

file before 5.19 does not properly restrict the amount of data read during a regex search, which allows remote attackers to cause a denial of service (CPU consumption) via a crafted file that triggers backtracking during processing of an awk rule, due to an incomplete fix for CVE-2013-7345 (CVE-2014-3538).

Integer overflow in the cdf_read_property_info function in cdf.c in file through 5.19, as used in the Fileinfo component in PHP before 5.4.32 and 5.5.x before 5.5.16, allows remote attackers to cause a denial of service (application crash) via a crafted CDF file. NOTE:
this vulnerability exists because of an incomplete fix for CVE-2012-1571 (CVE-2014-3587).

Multiple buffer overflows in the php_parserr function in ext/standard/dns.c in PHP before 5.4.32 and 5.5.x before 5.5.16 allow remote DNS servers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted DNS record, related to the dns_get_record function and the dn_expand function. NOTE: this issue exists because of an incomplete fix for CVE-2014-4049 (CVE-2014-3597).

An integer overflow flaw in PHP's unserialize() function was reported.
If unserialize() were used on untrusted data, this issue could lead to a crash or potentially information disclosure (CVE-2014-3669).

A heap corruption issue was reported in PHP's exif_thumbnail() function. A specially crafted JPEG image could cause the PHP interpreter to crash or, potentially, execute arbitrary code (CVE-2014-3670).

If client-supplied input was passed to PHP's cURL client as a URL to download, it could return local files from the server due to improper handling of null bytes (PHP#68089).

An out-of-bounds read flaw was found in file's donote() function in the way the file utility determined the note headers of a elf file.
This could possibly lead to file executable crash (CVE-2014-3710).

A use-after-free flaw was found in PHP unserialize(). An untrusted input could cause PHP interpreter to crash or, possibly, execute arbitrary code when processed using unserialize() (CVE-2014-8142).

Double free vulnerability in the zend_ts_hash_graceful_destroy function in zend_ts_hash.c in the Zend Engine in PHP before 5.5.21 allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors (CVE-2014-9425).

sapi/cgi/cgi_main.c in the CGI component in PHP before 5.5.21, when mmap is used to read a .php file, does not properly consider the mapping's length during processing of an invalid file that begins with a # character and lacks a newline character, which causes an out-of-bounds read and might allow remote attackers to obtain sensitive information from php-cgi process memory by leveraging the ability to upload a .php file or trigger unexpected code execution if a valid PHP script is present in memory locations adjacent to the mapping (CVE-2014-9427).

Use after free vulnerability in unserialize() in PHP before 5.5.21 (CVE-2015-0231).

Free called on an uninitialized pointer in php-exif in PHP before 5.5.21 (CVE-2015-0232).

The readelf.c source file has been removed from PHP's bundled copy of file's libmagic, eliminating exposure to denial of service issues in ELF file parsing such as CVE-2014-8116, CVE-2014-8117, CVE-2014-9620 and CVE-2014-9621 in PHP's fileinfo module.

S. Paraschoudis discovered that PHP incorrectly handled memory in the enchant binding. A remote attacker could use this issue to cause PHP to crash, resulting in a denial of service, or possibly execute arbitrary code (CVE-2014-9705).

Taoguang Chen discovered that PHP incorrectly handled unserializing objects. A remote attacker could use this issue to cause PHP to crash, resulting in a denial of service, or possibly execute arbitrary code (CVE-2015-0273).

It was discovered that PHP incorrectly handled memory in the phar extension. A remote attacker could use this issue to cause PHP to crash, resulting in a denial of service, or possibly execute arbitrary code (CVE-2015-2301).

Use-after-free vulnerability in the process_nested_data function in ext/standard/var_unserializer.re in PHP before 5.4.37, 5.5.x before 5.5.21, and 5.6.x before 5.6.5 allows remote attackers to execute arbitrary code via a crafted unserialize call that leverages improper handling of duplicate numerical keys within the serialized properties of an object. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-8142 (CVE-2015-0231).

The exif_process_unicode function in ext/exif/exif.c in PHP before 5.4.37, 5.5.x before 5.5.21, and 5.6.x before 5.6.5 allows remote attackers to execute arbitrary code or cause a denial of service (uninitialized pointer free and application crash) via crafted EXIF data in a JPEG image (CVE-2015-0232).

An integer overflow flaw, leading to a heap-based buffer overflow, was found in the way libzip, which is embedded in PHP, processed certain ZIP archives. If an attacker were able to supply a specially crafted ZIP archive to an application using libzip, it could cause the application to crash or, possibly, execute arbitrary code (CVE-2015-2331).

It was discovered that the PHP opcache component incorrectly handled memory. A remote attacker could possibly use this issue to cause PHP to crash, resulting in a denial of service, or possibly execute arbitrary code (CVE-2015-1351).

It was discovered that the PHP PostgreSQL database extension incorrectly handled certain pointers. A remote attacker could possibly use this issue to cause PHP to crash, resulting in a denial of service, or possibly execute arbitrary code (CVE-2015-1352).

PHP contains a bundled copy of the file utility's libmagic library, so it was vulnerable to the libmagic issues.

The updated php packages have been patched and upgraded to the 5.5.23 version which is not vulnerable to these issues. The libzip packages has been patched to address the CVE-2015-2331 flaw.

A bug in the php zip extension that could cause a crash has been fixed (mga#13820)

Additionally the jsonc and timezonedb packages has been upgraded to the latest versions and the PECL packages which requires so has been rebuilt for php-5.5.23.

Versions of PHP 5.4.x earlier than 5.4.28, or 5.5.x earlier than 5.5.12 are exposed to a flaw that exists within the FastCGI Process Manager (FPM) when setting permissions for a Unix socket. This could allow a remote attacker to gain elevated privileges after gaining access to the socket.

According to its banner, the version of PHP installed on the remote host is a development version of 5.6.0. It is, therefore, affected by multiple vulnerabilities.

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

The remote host is running a version of Mac OS X that is older than 10.9.5, and is thus missing security-related fixes for the following components:

  - Bluetooth
  - CoreGraphics
  - Foundation
  - IOAcceleratorFamily
  - IOHIDFamily
  - IOKit
  - Intel Graphics Driver
  - Kernel
  - Libnotify
  - OpenSSL
  - QT Media Foundation
  - apache_mod_php
  - ruby

Note that successful exploitation of the most serious issues could result in arbitrary code execution.

The remote host is running a version of Mac OS X 10.9.x that is prior to version 10.9.5. This update contains several security-related fixes for the following components :

  - apache_mod_php
  - Bluetooth
  - CoreGraphics
  - Foundation
  - Intel Graphics Driver
  - IOAcceleratorFamily
  - IOHIDFamily
  - IOKit
  - Kernel
  - Libnotify
  - OpenSSL
  - QT Media Foundation
  - ruby

Note that successful exploitation of the most serious issues can result in arbitrary code execution.

The remote host is affected by the vulnerability described in GLSA-201408-11 (PHP: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in PHP. Please review the       CVE identifiers referenced below for details.
  Impact :

    A context-dependent attacker can cause arbitrary code execution, create       a Denial of Service condition, read or write arbitrary files, impersonate       other servers, hijack a web session, or have other unspecified impact.
      Additionally, a local attacker could gain escalated privileges.
  Workaround :

    There is no known workaround at this time.

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2254-1 advisory.

    Christian Hoffmann discovered that the PHP FastCGI Process Manager (FPM) set incorrect permissions on the     UNIX socket. A local attacker could use this issue to possibly elevate their privileges. This issue only     affected Ubuntu 12.04 LTS, Ubuntu 13.10, and Ubuntu 14.04 LTS. (CVE-2014-0185)

    Francisco Alonso discovered that the PHP Fileinfo component incorrectly handled certain CDF documents. A     remote attacker could use this issue to cause PHP to hang or crash, resulting in a denial of service.
    (CVE-2014-0237, CVE-2014-0238)

    Stefan Esser discovered that PHP incorrectly handled DNS TXT records. A remote attacker could use this     issue to cause PHP to crash, resulting in a denial of service, or possibly execute arbitrary code.
    (CVE-2014-4049)

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.

php5 was updated to fix several security issues.

These issues were fixed :

  - Performance degradation by too many file_printf calls     (CVE-2014-0237)

  - DoS in Fileinfo component (CVE-2014-0238)

  - NULL pointer dereference in GD XPM decoder     (CVE-2014-2497)

  - Privilege escalation due to insecure default config     (CVE-2014-0185)

New php packages are available for Slackware 13.0, 13.1, 13.37, 14.0, 14.1, and -current to fix security issues.

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

  - CVE-2014-0185     The default PHP FPM socket permission has been changed     from 0666 to 0660 to mitigate a security vulnerability (     CVE-2014-0185 ) in PHP FPM that allowed any local user     to run a PHP code under the active user of FPM process     via crafted FastCGI client.

  The default Debian setup now correctly sets the listen.owner and   listen.group to www-data:www-data in default php-fpm.conf. If you   have more FPM instances or a webserver not running under www-data   user you need to adjust the configuration of FPM pools in   /etc/php5/fpm/pool.d/ so the accessing process has rights to access   the socket.

  - CVE-2014-0237 / CVE-2014-0238     Denial of service in the CDF parser of the fileinfo     module.

  - CVE-2014-2270     Denial of service in the fileinfo module.

A vulnerability has been discovered and corrected in php :

PHP FPM in PHP versions before 5.4.28 and 5.5.12 uses a UNIX domain socket with world-writable permissions by default, which allows any local user to connect to it and execute PHP scripts as the apache user (CVE-2014-0185).

The updated php packages have been upgraded to the 5.5.12 version which is not vulnerable to this issue.

Additionally, the timezonedb packages has been upgraded to the latest 2014.3 version, the php-suhosin packages has been upgraded to the latest 0.9.35 version which has better support for php-5.5 and the PECL packages which requires so has been rebuilt for php-5.5.12.

Notice: to fix CVE-2014-0185 this version change default php-fpm unix domain socket permission to 660 (instead of 666). Check your configuration if php-fpm use UDS (default configuration use a network socket).
