In PHP before 5.6.31, 7.x before 7.0.17, and 7.1.x before 7.1.3, remote attackers could cause a CPU consumption denial of service attack by injecting long form variables, related to main/php_variables.c.

According to its banner, the version of PHP running on the remote web server is 7.1.x prior to 7.1.3. It is, therefore, affected by a denial of service condition in PHP when handling overlarge POST requests. An unauthenticated, remote attacker can exploit this to exhaust available CPU resources.

Note that Nessus 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 web server is 5.6.x prior to 5.6.31. It is, therefore, affected by the following vulnerabilities :

 - An out-of-bounds read error exists in the PCRE library in the compile_bracket_matchingpath() function within file pcre_jit_compile.c. An unauthenticated, remote attacker can exploit this, via a specially crafted regular expression, to crash a process linked to the library, resulting in a denial of service condition. (CVE-2017-6004)

 - An out-of-bounds read error exists in the GD Graphics Library (LibGD) in the gdImageCreateFromGifCtx() function within file gd_gif_in.c when handling a specially crafted GIF file. An unauthenticated, remote attacker can exploit this to disclose sensitive memory contents or crash a process linked to the library. (CVE-2017-7890)

 - An out-of-bounds read error exists in Oniguruma in the match_at() function within file regexec.c. An unauthenticated, remote attacker can exploit this to disclose sensitive memory contents or crash a process linked to the library. (CVE-2017-9224)

 - An out-of-bounds write error exists in Oniguruma in the next_state_val() function during regular expression compilation. An unauthenticated, remote attacker can exploit this to execute arbitrary code. (CVE-2017-9226)

 - An out-of-bounds read error exists in Oniguruma in the mbc_enc_len() function within file utf8.c. An unauthenticated, remote attacker can exploit this to disclose memory contents or crash a process linked to the library. (CVE-2017-9227)

 - An out-of-bounds write error exists in Oniguruma in the bitset_set_range() function during regular expression compilation. An unauthenticated, remote attacker can exploit this to execute arbitrary code. (CVE-2017-9228)

 - An invalid pointer deference flaw exists in Oniguruma in the left_adjust_char_head() function within file regexec.c during regular expression compilation. An unauthenticated, remote attacker can exploit this to crash a process linked to the library, resulting in a denial of service condition. (CVE-2017-9229)

 - A denial of service condition exists in PHP when handling overlarge POST requests. An unauthenticated, remote attacker can exploit this to exhaust available CPU resources. (CVE-2017-11142)

 - An extended invalid free error exists in PHP in the php_wddx_push_element() function within file ext/wddx/wddx.c when parsing empty boolean tags. An unauthenticated, remote attacker can exploit this to cause a denial of service condition. (CVE-2017-11143)

 - A flaw exists in OpenSSL in the EVP_SealInit() function within file crypto/evp/p_seal.c due to returning an undocumented value of '-1'. An unauthenticated, remote attacker can exploit this to cause an unspecified impact. (CVE-2017-11144)

 - An out-of-bounds read error exists in PHP in the php_parse_date() function within file ext/date/lib/parse_date.c. An unauthenticated, remote attacker can exploit this to disclose memory contents or cause a denial of service condition. (CVE-2017-11145)

 - An out-of-bounds read error exists in PHP in the finish_nested_data() function within file ext/standard/var_unserializer.re. An unauthenticated, remote attacker can exploit this to disclose memory contents or cause a denial of service condition.

 - An off-by-one overflow condition exists in PHP in the INI parsing API, specifically in the zend_ini_do_op() function within file Zend/zend_ini_parser.y, due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code.

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

  - CVE-2017-7890: Buffer over-read from unitialized data in     gdImageCreateFromGifCtx function could lead to denial of     service (bsc#1050241)

  - CVE-2016-5766: Integer Overflow in _gd2GetHeader()     resulting in heap overflow could lead to denial of     service or code execution (bsc#986386) Other fixes :

  - Soap Request with References (bsc#1053645)

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

Several vulnerabilities were found in PHP, a widely-used open source general purpose scripting language :

  - CVE-2017-11142     Denial of service via overly long form variables

  - CVE-2017-11143     Invalid free() in wddx_deserialize()

  - CVE-2017-11144     Denial of service in openssl extension due to incorrect     return value check of OpenSSL sealing function.

  - CVE-2017-11145     Out-of-bounds read in wddx_deserialize()

  - CVE-2017-11628     Buffer overflow in PHP INI parsing API
