PHP 5.6.x < 5.6.7 Multiple Vulnerabilities

According to its banner, the version of PHP 5.6.x installed on the remote host is prior to 5.6.7. It is, therefore, affected by multiple vulnerabilities :

• A use-after-free error exists related to function ‘unserialize’, which can allow a remote attacker to execute arbitrary code. Note that this issue is due to an incomplete fix for CVE-2014-8142. (CVE-2015-0231)

• An integer overflow error exists in function ‘regcomp’ in the Henry Spencer regex library, due to improper validation of user-supplied input. An attacker can exploit this to cause a denial of service or to execute arbitrary code. (CVE-2015-2305)

• An integer overflow error exists in the ‘_zip_cdir_new’ function, due to improper validation of user-supplied input. An attacker, using a crafted ZIP archive, can exploit this to cause a denial of service or to execute arbitrary code. (CVE-2015-2331)

• A filter bypass vulnerability exists due to a flaw in the move_uploaded_file() function in which pathnames are truncated when a NULL byte is encountered. This allows a remote attacker, via a crafted second argument, to bypass intended extension restrictions and create files with unexpected names. (CVE-2015-2348)

• A user-after-free error exists in the process_nested_data() function. This allows a remote attacker, via a crafted unserialize call, to dereference already freed memory, resulting in the execution of arbitrary code. (CVE-2015-2787)

Note that the scanner has not attempted to exploit these issues but has instead relied only on the application’s self-reported version number.
