Stack consumption vulnerability in Zend/zend_exceptions.c in PHP before 5.4.44, 5.5.x before 5.5.28, and 5.6.x before 5.6.12 allows remote attackers to cause a denial of service (segmentation fault) via recursive method calls.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Stack consumption vulnerability in Zend/zend_exceptions.c in PHP before 5.4.44, 5.5.x before 5.5.28, and     5.6.x before 5.6.12 allows remote attackers to cause a denial of service (segmentation fault) via     recursive method calls. (CVE-2015-8873)

Note that Nessus relies on the presence of the package as reported by the vendor.

According to the versions of the php packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - A flaws was discovered in the way PHP performed object     unserialization. Specially crafted input processed by     the unserialize() function could cause a PHP     application to crash or, possibly, execute arbitrary     code.(CVE-2014-8142)

  - It was found that certain PHP functions did not     properly handle file names containing a NULL character.
    A remote attacker could possibly use this flaw to make     a PHP script access unexpected files and bypass     intended file system access     restrictions.(CVE-2015-4026)

  - A flaw was discovered in the way PHP performed object     unserialization. Specially crafted input processed by     the unserialize() function could cause a PHP     application to crash or, possibly, execute arbitrary     code.(CVE-2015-6834)

  - It was found that certain PHP functions did not     properly handle file names containing a NULL character.
    A remote attacker could possibly use this flaw to make     a PHP script access unexpected files and bypass     intended file system access     restrictions.(CVE-2015-4025)

  - It was found that PHP's gd extension did not properly     handle file names with a null character. A remote     attacker could possibly use this flaw to make a PHP     application access unexpected files and bypass intended     file system access restrictions.(CVE-2014-5120)

  - A flaw was discovered in the way PHP performed object     unserialization. Specially crafted input processed by     the unserialize() function could cause a PHP     application to crash or, possibly, execute arbitrary     code.(CVE-2015-6835)

  - Stack consumption vulnerability in     Zend/zend_exceptions.c in PHP before 5.4.44, 5.5.x     before 5.5.28, and 5.6.x before 5.6.12 allows remote     attackers to cause a denial of service (segmentation     fault) via recursive method calls.(CVE-2015-8873)

  - An uninitialized pointer use flaw was found in PHP's     Exif extension. A specially crafted JPEG or TIFF file     could cause a PHP application using the     exif_read_data() function to crash or, possibly,     execute arbitrary code with the privileges of the user     running that PHP application.(CVE-2015-0232)

  - A buffer over-read flaw was found in PHP's phar (PHP     Archive) paths implementation. A malicious script     author could possibly use this flaw to disclose certain     portions of server memory.(CVE-2015-2783)

  - A use-after-free flaw was found in the unserialize()     function of PHP's DateTimeZone implementation. A     malicious script author could possibly use this flaw to     disclose certain portions of server     memory.(CVE-2015-0273)

  - 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 crash a PHP application that used the     dns_get_record() function to perform a DNS     query.(CVE-2014-3597)

  - 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)

  - Integer overflow in the ftp_genlist function in     ext/ftp/ftp.c in PHP before 5.4.42, 5.5.x before     5.5.26, and 5.6.x before 5.6.10 allows remote FTP     servers to execute arbitrary code via a long reply to a     LIST command, leading to a heap-based buffer overflow.
    NOTE: this vulnerability exists because of an     incomplete fix for CVE-2015-4022.(CVE-2015-4643)

  - 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)

This update was imported from the SUSE:SLE-12:Update update project.

According to its banner, the version of PHP running on the remote web server is 5.5.x prior to 5.5.28. It is, therefore, affected by multiple vulnerabilities :

  - Multiple use-after-free errors exist in spl_array.c,     spl_observer.c, and spl_dllist.c due to improper     sanitization of input to the unserialize() function. An     attacker can exploit these issues, by using a specially     crafted SplDoublyLinkedList, SplArrayObject, or     SplObjectStorage object, to deference freed memory and     thus execute arbitrary code. (CVE-2015-6831)

  - A dangling pointer error exists in file spl_array.c due     to improper sanitization of input to the unserialize()     function. An attacker can exploit this, by using a     specially crafted SplDoublyLinkedList object, to gain     control over a deallocated pointer and thus execute     arbitrary code. (CVE-2015-6832)

  - A path traversal flaw exists in file phar_object.c due     to improper sanitization of user-supplied input. An     attacker can exploit this to write arbitrary files.
    (CVE-2015-6833)

  - A type confusion flaw exists in the     serialize_function_call() function in soap.c due to     improper validation of input passed via the header     field. A remote attacker can exploit this to execute     arbitrary code. (CVE-2015-6836)

  - Multiple type confusion flaws exist in the _call()     method in file php_http.c when handling calls for     zend_hash_get_current_key or 'Z*'. An attacker can     exploit this to disclose memory contents or crash     an application using PHP. (CVE-2015-8835)

  - The openssl_random_pseudo_bytes() function in file     openssl.c does not generate sufficiently random numbers.
    This allows an attacker to more easily predict the     results, thus allowing further attacks to be carried     out. (CVE-2015-8867)

  - A flaw exists in file zend_exceptions.c due to the     improper use of the function unserialize() during     recursive method calls. A remote attacker can exploit     this to crash an application using PHP. (CVE-2015-8873)

  - A flaw exists in file zend_exceptions.c due to     insufficient type checking by functions unserialize()     and __toString(). A remote attacker can exploit this to     cause a NULL pointer deference or unexpected method     execution, thus causing an application using PHP to     crash. (CVE-2015-8876)

  - An integer truncation flaw exists in the     zend_hash_compare() function in zend_hash.c that is     triggered when comparing arrays. A remote attacker can     exploit this to cause arrays to be improperly matched     during comparison.
    Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
