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.

(CVE-2014-0237, CVE-2014-0238, CVE-2014-3479, CVE-2014-3480, CVE-2012-1571)

Two denial of service flaws were found in the way the File Information (fileinfo) extension handled indirect and search rules. A remote attacker could use either of these flaws to cause a PHP application using fileinfo to crash or consume an excessive amount of CPU.
(CVE-2014-1943, CVE-2014-2270)

A heap-based buffer overflow flaw was found in the way PHP parsed DNS TXT records. 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-2014-4049)

A type confusion issue was found in PHP's phpinfo() function. A malicious script author could possibly use this flaw to disclose certain portions of server memory. (CVE-2014-4721)

A buffer over-read flaw was found in the way the DateInterval class parsed interval specifications. An attacker able to make a PHP application parse a specially crafted specification using DateInterval could possibly cause the PHP interpreter to crash. (CVE-2013-6712)

A type confusion issue was found in the SPL ArrayObject and SPLObjectStorage classes' unserialize() method. A remote attacker able to submit specially crafted input to a PHP application, which would then unserialize this input using one of the aforementioned methods, could use this flaw to execute arbitrary code with the privileges of the user running that PHP application. (CVE-2014-3515)

The CVE-2014-0237, CVE-2014-0238, CVE-2014-3479, and CVE-2014-3480 issues were discovered by Francisco Alonso of Red Hat Product Security.

All php53 and php users are advised to upgrade to these updated packages, which contain backported patches to correct these issues.

php5 was updated to fix security issues :

CVE-2014-4670: 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-2014-4698: 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-2014-4721: 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)

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).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Updated php packages fix security vulnerabilities :

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).

PHP contains a bundled copy of the file utility's libmagic library, so it was vulnerable to this issue. It has been updated to versions 5.5.14, which fix this issue and several other bugs.

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).

Additionally, php-apc has been rebuilt against the updated php packages and the php-timezonedb packages has been upgraded to the 2014.5 version.

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-2014-0207     Francisco Alonso of the Red Hat Security Response Team     reported an incorrect boundary check in the     cdf_read_short_sector() function.

  - CVE-2014-3478     Francisco Alonso of the Red Hat Security Response Team     discovered a flaw in the way the truncated pascal string     size in the mconvert() function is computed.
