Synopsis

PHP 7.1.x < 7.1.7 Multiple Vulnerabilities

Description

According to its banner, the version of PHP running on the remote web server is 7.1.x prior to 7.1.7. It is, therefore, affected by the following vulnerabilities :

 - 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 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)

 - 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)

 - 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. (CVE-2017-11628)

 - 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)

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

Solution

Upgrade to PHP version 7.1.7 or later.
