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

  - In PHP before 5.6.31, 7.x before 7.0.21, and 7.1.x before 7.1.7, the openssl extension PEM sealing code     did not check the return value of the OpenSSL sealing function, which could lead to a crash of the PHP     interpreter, related to an interpretation conflict for a negative number in ext/openssl/openssl.c, and an     OpenSSL documentation omission. (CVE-2017-11144)

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

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.

  - A Heap buffer overread flaw in finish_nested_data     while unserializing untrusted data could lead to an     unspecified impact on the integrity of PHP.
    (CVE-2017-12933)

  - A stack-based buffer overflow in the zend_ini_do_op()     function in Zend/zend_ini_parser.c could cause a denial     of service or potentially allow executing code.
    (CVE-2017-11628)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

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 7.0.x prior to 7.0.21. 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 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)

  - A stack-based buffer overflow condition exists in PHP     in the msgfmt_parse_message() function due to improper     validation of user-supplied input when parsing locale.
    An unauthenticated, remote attacker can exploit this to     cause a denial of service condition or the execution of     arbitrary code. (CVE-2017-11362)

  - 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.c, 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. (CVE-2017-11628)

  - 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.
    (CVE-2017-12933)

  - A use-after-free error exists in PHP in the     zval_get_type() function within file     ext/standard/var_unserializer.c. An unauthenticated,     remote attacker can exploit this to execute arbitrary     code. (CVE-2017-12934)

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