Integer overflow in the _zip_cdir_new function in zip_dirent.c in libzip 0.11.2 and earlier, as used in the ZIP extension in PHP before 5.4.39, 5.5.x before 5.5.23, and 5.6.x before 5.6.7 and other products, allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a ZIP archive that contains many entries, leading to a heap-based buffer overflow.

According to its banner, the version of PHP 5.6.x installed on the remote host is prior to 5.6.7. It is, therefore, affected by multiple vulnerabilities :

 - A use-after-free error exists related to function 'unserialize', which can allow a remote attacker to execute arbitrary code. Note that this issue is due to an incomplete fix for CVE-2014-8142. (CVE-2015-0231)

 - An integer overflow error exists in function 'regcomp' in the Henry Spencer regex library, due to improper validation of user-supplied input. An attacker can exploit this to cause a denial of service or to execute arbitrary code. (CVE-2015-2305)

 - An integer overflow error exists in the '_zip_cdir_new' function, due to improper validation of user-supplied input. An attacker, using a crafted ZIP archive, can exploit this to cause a denial of service or to execute arbitrary code. (CVE-2015-2331)

 - A filter bypass vulnerability exists due to a flaw in the move_uploaded_file() function in which pathnames are truncated when a NULL byte is encountered. This allows a remote attacker, via a crafted second argument, to bypass intended extension restrictions and create files with unexpected names. (CVE-2015-2348)

 - A user-after-free error exists in the process_nested_data() function. This allows a remote attacker, via a crafted unserialize call, to dereference already freed memory, resulting in the execution of arbitrary code. (CVE-2015-2787)

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

Libzip was updated to fix one security issue.

A zip file with an unusually large number of entries could have caused an integer overflow leading to a write past the heap boundary, crashing the application. (CVE-2015-2331 bnc#923240)

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.

Multiple vulnerabilities has been discovered and corrected in php :

libzip developers report :

Avoid integer overflow. Fixed similarly to patch used in PHP copy of libzip.

According to its banner, the version of PHP 5.6.x installed on the remote host is prior to 5.6.7. It is, therefore, affected by multiple vulnerabilities :

  - A use-after-free error exists related to function     'unserialize', which can allow a remote attacker to     execute arbitrary code. Note that this issue is due to     an incomplete fix for CVE-2014-8142. (CVE-2015-0231)

  - An integer overflow error exists in function 'regcomp'     in the Henry Spencer regex library, due to improper     validation of user-supplied input. An attacker can     exploit this to cause a denial of service or to execute     arbitrary code. (CVE-2015-2305)

  - An integer overflow error exists in the '_zip_cdir_new'     function, due to improper validation of user-supplied     input. An attacker, using a crafted ZIP archive, can     exploit this to cause a denial of service or to execute     arbitrary code. (CVE-2015-2331)

  - A filter bypass vulnerability exists due to a flaw in     the move_uploaded_file() function in which pathnames are     truncated when a NULL byte is encountered. This allows a     remote attacker, via a crafted second argument, to     bypass intended extension restrictions and create files     with unexpected names. (CVE-2015-2348)

  - A user-after-free error exists in the     process_nested_data() function. This allows a remote     attacker, via a crafted unserialize call, to dereference     already freed memory, resulting in the execution of     arbitrary code. (CVE-2015-2787)

  - A type confusion vulnerability in the     SoapClient's __call() function in ext/soap/soap.c     could allow a remote attacker to execute arbitrary     code by providing crafted serialized data with an     unexpected data type (CVE-2015-4147, CVE-2015-4148)

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