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.

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

It was found that the fix for CVE-2012-1571 was incomplete; the File Information (fileinfo) extension did not correctly parse certain Composite Document Format (CDF) files. A remote attacker could use this flaw to crash a PHP application using fileinfo via a specially crafted CDF file. (CVE-2014-3587)

A NULL pointer dereference flaw was found in the gdImageCreateFromXpm() function of PHP's gd extension. A remote attacker could use this flaw to crash a PHP application using gd via a specially crafted X PixMap (XPM) file. (CVE-2014-2497)

Multiple buffer over-read flaws were found in the php_parserr() function of PHP. A malicious DNS server or a man-in-the-middle attacker could possibly use this flaw to execute arbitrary code as the PHP interpreter if a PHP application used the dns_get_record() function to perform a DNS query. (CVE-2014-3597)

Two use-after-free flaws were found in the way PHP handled certain Standard PHP Library (SPL) Iterators and ArrayIterators. A malicious script author could possibly use either of these flaws to disclose certain portions of server memory. (CVE-2014-4670, CVE-2014-4698)

The CVE-2014-3597 issue was discovered by David Kutlek of the Red Hat BaseOS QE.

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.

Versions of PHP 5.5.x earlier than 5.5.16, or PHP 5.4.x earlier than 5.4.32 are prone to multiple vulnerabilities, some of which include:

  - LibGD contains a NULL pointer dereference flaw in the 'gdxpm.c' file, which could be leveraged to cause denial of service. (CVE-2014-2497)

  - Denial of service related to an insufficient patch for CVE-2013-7345; it is still possible for an attacker to cause denial of service via a crafted input file that causes excessive matching by awk regular expression rules. (CVE-2014-3538)

  - An integer overflow flaw exists in the 'cdf.c' file, which could be leveraged via a specially crafted CDF file to cause denial of service. (CVE-2014-3587)

  - There are multiple buffer overflow flaws in the 'dns.c' file related to the 'dns_get_record' and 'dn_expand' functions. By using a specially crafted DNS record, a remote attacker could exploit these to cause a denial of service or execute arbitrary code. (CVE-2014-3597)

  - Several use-after-free issues in the SPL component that could be leveraged to cause a denial of service. (CVE-2014-4670, CVE-2014-4698)

  - There exist multiple flaws in the GD component within the 'gd_ctx.c' file where user-supplied input is not properly validated to ensure that pathnames lack %00 sequences. By using specially crafted input, a remote attacker could overwrite arbitrary files. (CVE-2014-5120)

According to its banner, the remote web server is running a version of PHP 5.4.x prior to 5.4.32. It is, therefore, affected by the following vulnerabilities :

  - LibGD contains a NULL pointer dereference flaw in its     'gdImageCreateFromXpm' function in the 'gdxpm.c' file.
    By using a specially crafted color mapping, a remote     attacker could cause a denial of service.
    (CVE-2014-2497)

  - The original upstream patch for CVE-2013-7345 did not     provide a complete solution. It is, therefore, still     possible for a remote attacker to deploy a specially     crafted input file to cause excessive resources to be     used when trying to detect the file type using awk     regular expression rules. This can cause a denial of     service. (CVE-2014-3538)

  - An integer overflow flaw exists in the 'cdf.c' file. By     using a specially crafted CDF file, a remote attacker     could cause a denial of service. (CVE-2014-3587)

  - There are multiple buffer overflow flaws in the 'dns.c'     file related to the 'dns_get_record' and 'dn_expand'     functions. By using a specially crafted DNS record,     a remote attacker could exploit these to cause a denial     of service or execute arbitrary code. (CVE-2014-3597)

  - A flaw exists in the 'spl_dllist.c' file that may lead     to a use-after-free condition in the SPL component when     iterating over an object. An attacker could utilize this     to cause a denial of service. (CVE-2014-4670)

  - A flaw exists in the 'spl_array.c' file that may lead to     a use-after-free condition in the SPL component when     handling the modification of objects while sorting. An     attacker could utilize this to cause a denial of     service. (CVE-2014-4698)

  - There exist multiple flaws in the GD component within     the 'gd_ctx.c' file where user-supplied input is not     properly validated to ensure that pathnames lack %00     sequences. By using specially crafted input, a remote     attacker could overwrite arbitrary files.
    (CVE-2014-5120)

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

Several vulnerabilities were found in PHP, a general-purpose scripting language commonly used for web application development. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2014-3538     It was discovered that the original fix for     CVE-2013-7345 did not sufficiently address the problem.
    A remote attacker could still cause a denial of service     (CPU consumption) via a specially crafted input file     that triggers backtracking during processing of an awk     regular expression rule.

  - CVE-2014-3587     It was discovered that the CDF parser of the fileinfo     module does not properly process malformed files in the     Composite Document File (CDF) format, leading to     crashes.

  - CVE-2014-3597     It was discovered that the original fix for     CVE-2014-4049 did not completely address the issue. A     malicious server or man-in-the-middle attacker could     cause a denial of service (crash) and possibly execute     arbitrary code via a crafted DNS TXT record.

  - CVE-2014-4670     It was discovered that PHP incorrectly handled certain     SPL Iterators. A local attacker could use this flaw to     cause PHP to crash, resulting in a denial of service.

Multiple vulnerabilities has been discovered and corrected in php :

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. NOTE: this vulnerability exists because of an incomplete fix for CVE-2013-7345 (CVE-2014-3538).

CVE-2014-4721: The phpinfo implementation in ext/standard/info.c in PHP did not ensure use of the string data type for the PHP_AUTH_PW, PHP_AUTH_TYPE, PHP_AUTH_USER, and PHP_SELF variables, which might allow context-dependent attackers to obtain sensitive information from process memory by using the integer data type with crafted values, related to a 'type confusion' vulnerability, as demonstrated by reading a private SSL key in an Apache HTTP Server web-hosting environment with mod_ssl and a PHP 5.3.x mod_php.

PHP 5.3 has been updated to fix several security problems :

  - The SPL component in PHP incorrectly anticipated that     certain data structures will have the array data type     after unserialization, which allowed remote attackers to     execute arbitrary code via a crafted string that     triggers use of a Hashtable destructor, related to 'type     confusion' issues in (1) ArrayObject and (2)     SPLObjectStorage. (CVE-2014-3515)

  - The cdf_read_short_sector function in cdf.c in file     before 5.19, as used in the Fileinfo component in PHP     allowed remote attackers to cause a denial of service     (assertion failure and application exit) via a crafted     CDF file. (CVE-2014-0207)

  - Buffer overflow in the mconvert function in softmagic.c     in file before 5.19, as used in the Fileinfo component     in PHP allowed remote attackers to cause a denial of     service (application crash) via a crafted Pascal string     in a FILE_PSTRING conversion. (CVE-2014-3478)

  - The cdf_check_stream_offset function in cdf.c in file     before 5.19, as used in the Fileinfo component in PHP     relied on incorrect sector-size data, which allowed     remote attackers to cause a denial of service     (application crash) via a crafted stream offset in a CDF     file. (CVE-2014-3479)

  - The cdf_count_chain function in cdf.c in file before     5.19, as used in the Fileinfo component in PHP did not     properly validate sector-count data, which allowed     remote attackers to cause a denial of service     (application crash) via a crafted CDF file.
    (CVE-2014-3480)

  - The cdf_read_property_info function in file before 5.19,     as used in the Fileinfo component in PHP did not     properly validate a stream offset, which allowed remote     attackers to cause a denial of service (application     crash) via a crafted CDF file. (CVE-2014-3487)

  - Use-after-free vulnerability in ext/spl/spl_dllist.c in     the SPL component in PHP allowed 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)

  - Use-after-free vulnerability in ext/spl/spl_array.c in     the SPL component in PHP allowed 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)

  - The phpinfo implementation in ext/standard/info.c in PHP     did not ensure use of the string data type for the     PHP_AUTH_PW, PHP_AUTH_TYPE, PHP_AUTH_USER, and PHP_SELF     variables, which might allow context-dependent attackers     to obtain sensitive information from process memory by     using the integer data type with crafted values, related     to a 'type confusion' vulnerability, as demonstrated by     reading a private SSL key in an Apache HTTP Server     web-hosting environment with mod_ssl and a PHP 5.3.x     mod_php. (CVE-2014-4721)

According to its banner, the version of PHP 5.5.x in use on the remote web server is a version prior to 5.5.15. It is, therefore, affected by the following vulnerabilities :

  - A use-after-free error exists in the file     'ext/spl/spl_dllist.c' related to the Standard PHP     Library (SPL). Using a specially crafted iterator,     an attacker could cause a denial of service condition     or other unspecified impacts. (CVE-2014-4670)

  - A use-after-free error exists in the file     'ext/spl/spl_array.c' related to the Standard PHP     Library (SPL). This could allow an attacker, using     'ArrayObjects' or 'ArrayIterator', to cause a denial     of service condition or other unspecified impacts.
    (CVE-2014-4698)

  - The function 'sapi_cli_server_send_headers' in the file     'sapi/cli/php_cli_server.c' contains an error that does     not properly handle an empty 'header' parameter and     could allow denial of service attacks. Note that this     issue affects only the built-in command line development     server.

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

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2276-1 advisory.

    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-2014-0207, CVE-2014-3478, CVE-2014-3479, CVE-2014-3480, CVE-2014-3487)

    Stefan Esser discovered that PHP incorrectly handled unserializing SPL extension objects. An attacker     could use this issue to execute arbitrary code. (CVE-2014-3515)

    It was discovered that PHP incorrectly handled certain SPL Iterators. An attacker could use this issue to     cause PHP to crash, resulting in a denial of service. (CVE-2014-4670)

    It was discovered that PHP incorrectly handled certain ArrayIterators. An attacker could use this issue to     cause PHP to crash, resulting in a denial of service. (CVE-2014-4698)

    Stefan Esser discovered that PHP incorrectly handled variable types when calling phpinfo(). An attacker     could use this issue to possibly gain access to arbitrary memory, possibly containing sensitive     information. (CVE-2014-4721)

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.
