  - An information disclosure vulnerability exists because of a type confusion error. Specifically, this issue occurs when the 'unserialize()' function is used with SoapFault object's '__toString()' function. An attacker can exploit this issue to leak arbitrary memory blocks.
  - A flaw exists in the 'phar_parse_metadata()' function in 'ext/phar/phar.c'. The issue is triggered as user-supplied input is not properly validated when parsing a specially crafted TAR file. This may allow a remote attacker to corrupt memory and cause a denial of service or potentially execute arbitrary code. (CVE-2015-3307)
  - A type confusion flaw exists in the '__toString()' method in 'incomplete_class.c' that may allow a context-dependent attacker to leak arbitrary memory blocks or potentially cause a denial of service. (CVE-2015-4602)
  - Multiple unspecified issues exist in '/soap/php_http.c' and '/soap/php_encoding.c'. This may allow an attacker to have an unspecified impact. (CVE-2015-4601)
  - A denial of service vulnerability affects Fine Free File, a common component used in PHP known as 'file'. Specifically, this issue affects the source file 'libmagic/softmagic.c' because it fails to properly handle offsets that exceed 'bytecnt' or vice versa. (CVE-2015-4605)

    (CVE-2015-4602)

  - A type confusion error exists in the     exception::getTraceAsString() function within file     Zend/zend_exceptions.c that allows a remote attacker to     execute arbitrary code. (CVE-2015-4603)

  - A denial of service vulnerability exists due to a flaw     in the bundled libmagic library, specifically in the     mget() function within file softmagic.c. The function     fails to maintain a certain pointer relationship. An     unauthenticated, remote attacker can exploit this, via a     crafted string, to crash the application.
    (CVE-2015-4604)

  - A denial of service vulnerability exists due to a flaw     in the bundled libmagic library, specifically in the     mcopy() function within file softmagic.c. The function     fails to properly handle an offset that exceeds     'bytecnt'. An unauthenticated, remote attacker can     exploit this, via a crafted string, to crash the     application. (CVE-2015-4605)

  - A use-after-free error exists in the sqlite3_close()     function within file /ext/sqlite3/sqlite3.c when closing     database connections. An unauthenticated, remote     attacker can exploit this to execute arbitrary code.

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

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

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

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

A buffer overflow flaw was found in 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-2015-3329)

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).

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.
