sapi/fpm/fpm/fpm_log.c in PHP before 5.5.31, 5.6.x before 5.6.17, and 7.x before 7.0.2 misinterprets the semantics of the snprintf return value, which allows attackers to obtain sensitive information from process memory or cause a denial of service (out-of-bounds read and buffer overflow) via a long string, as demonstrated by a long URI in a configuration with custom REQUEST_URI logging.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - php: buffer overflow in handling of long link names in tar phar archives (CVE-2016-2554)

  - php: Uninitialized read in exif_process_IFD_in_TIFF (CVE-2019-9641)

  - The ip2long function in PHP 5.1.4 and earlier may incorrectly validate an arbitrary string and return a     valid network IP address, which allows remote attackers to obtain network information and facilitate other     attacks, as demonstrated using SQL injection in the X-FORWARDED-FOR Header in index.php in MiniBB 2.0.
    NOTE: it could be argued that the ip2long behavior represents a risk for security-relevant issues in a way     that is similar to strcpy's role in buffer overflows, in which case this would be a class of     implementation bugs that would require separate CVE items for each PHP application that uses ip2long in a     security-relevant manner. (CVE-2006-4023)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - php: buffer overflow in handling of long link names in tar phar archives (CVE-2016-2554)

  - php: Heap-based buffer over-read in mbstring regular expression functions (CVE-2019-9023)

  - Session fixation vulnerability in the Sessions subsystem in PHP before 5.5.2 allows remote attackers to     hijack web sessions by specifying a session ID. (CVE-2011-4718)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

According to its banner, the version of PHP running on the remote host is 5.6.x prior to 5.6.17. It is, therefore, affected by multiple vulnerabilities :

 - An out-of-bounds read error exists in the gdImageRotateInterpolated() function in file gd_interpolation.c when handling background colors. A remote attacker can exploit this to disclose memory contents or crash the application. (CVE-2016-1903)

 - An unspecified flaw exists in file fpm_log.c in the fpm_log_write() function when handling very long HTTP requests. A local attacker can exploit this to obtain sensitive information, via access to the access log file. (CVE-2016-5114)

 - A use-after-free error exists in file wddx.c in the php_wddx_pop_element() function when handling WDDX packet deserialization. A remote attacker can exploit this, by dereferencing already freed memory, to execute arbitrary code.

 - A type confusion flaw exists in file xmlrpc-epi-php.c in the PHP_to_XMLRPC_worker() function. A remote attacker can exploit this to disclose memory contents, crash the application process, or have other impact.

 - A type confusion flaw exists in file wddx.c when handling WDDX packet deserialization. A remote attacker can exploit this to execute arbitrary code.

 - A flaw exists in file lsapilib.c when handling requests due to the LSAPI module failing to clear its secrets in child processes. A remote attacker can exploit this to gain access to memory contents, resulting in the disclosure of sensitive information.

 - A flaw exists in file lsapilib.c in the parseRequest() function due to a failure to properly sanitize input passed through multiple, unspecified parameters. A remote attacker can exploit this to cause a denial of service.

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

According to its banner, the version of PHP running on the remote host is 7.x prior to 7.0.2. It is, therefore, affected by multiple vulnerabilities :

  - An out-of-bounds read error exists in the     gdImageRotateInterpolated() function in file     gd_interpolation.c when handling background colors.
    A remote attacker can exploit this to disclose memory     contents or crash the application. (CVE-2016-1903)

  - An integer overflow condition exists in file exec.c     in the escapeshellarg() and escapeshellcmd() functions     due to a failure to properly validate user-supplied     string input. A remote attacker can exploit this to     cause a heap-based overflow, resulting in a denial of     service or the execution of arbitrary code.
    (CVE-2016-1904)

  - A use-after-free error exists in file wddx.c in the     php_wddx_pop_element() function when handling WDDX     packet deserialization. A remote attacker can exploit     this, by dereferencing already freed memory, to execute     arbitrary code.

  - A type confusion flaw exists in file xmlrpc-epi-php.c     in the PHP_to_XMLRPC_worker() function. A remote     attacker can exploit this to disclose memory contents,     crash the application process, or have other impact.

  - A flaw exists in file lsapilib.c when handling requests     due to the LSAPI module failing to clear its secrets in     child processes. A remote attacker can exploit this to     gain access to memory contents, resulting in the     disclosure of sensitive information.

  - A flaw exists in file lsapilib.c in the parseRequest()     function due to a failure to properly sanitize input     passed through multiple, unspecified parameters. A     remote attacker can exploit this to cause a denial of     service.

According to its banner, the version of PHP running on the remote host is 5.5.x prior to 5.5.31 or 5.6.x prior to 5.6.17. It is, therefore, affected by multiple vulnerabilities :

  - An out-of-bounds read error exists in the     gdImageRotateInterpolated() function in file     gd_interpolation.c when handling background colors.
    A remote attacker can exploit this to disclose memory     contents or crash the application. (CVE-2016-1903)

  - An unspecified flaw exists in file fpm_log.c in the     fpm_log_write() function when handling very long     HTTP requests. A local attacker can exploit this to     obtain sensitive information, via access to the     access log file. (CVE-2016-5114)

  - A type confusion flaw exists in file xmlrpc-epi-php.c     in the PHP_to_XMLRPC_worker() function. A remote     attacker can exploit this to disclose memory contents,     crash the application process, or have other impact.

  - A type confusion flaw exists in file wddx.c when     handling WDDX packet deserialization. A remote attacker     can exploit this to execute arbitrary code.

  - A flaw exists in file lsapilib.c when handling requests     due to the LSAPI module failing to clear its secrets in     child processes. A remote attacker can exploit this to     gain access to memory contents, resulting in the     disclosure of sensitive information.
