According to its banner, the version of PHP 5.6.x running on the remote web server is prior to 5.6.10. It is, therefore, affected by multiple vulnerabilities :
Multiple heap buffer overflow conditions exist in the bundled Perl-Compatible Regular Expression (PCRE) library due to improper validation of user-supplied input to the compile_branch() and pcre_compile2() functions. A remote attacker can exploit these conditions to cause a heap-based buffer overflow, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2015-2325, CVE-2015-2326)
A denial of service vulnerability exists in the bundled SQLite component due to improper handling of quotes in collation sequence names. A remote attacker can exploit this to cause uninitialized memory access, resulting in denial of service condition.
(CVE-2015-3414)
A denial of service vulnerability exists in the bundled SQLite component due to an improper implementation of comparison operators in the sqlite3VdbeExec() function in vdbe.c. A remote attacker can exploit this to cause an invalid free operation, resulting in a denial of service condition. (CVE-2015-3415)
A denial of service vulnerability exists in the bundled SQLite component due to improper handling of precision and width values during floating-point conversions in the sqlite3VXPrintf() function in printf.c. A remote attacker can exploit this to cause a stack-based buffer overflow, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2015-3416)
A security bypass vulnerability exists due to a failure in multiple extensions to check for NULL bytes in a path when processing or reading a file. A remote attacker can exploit this, by combining the ‘\0’ character with a safe file extension, to bypass access restrictions.
(CVE-2015-4598)
An arbitrary command injection vulnerability exists due to a flaw in the php_escape_shell_arg() function in exec.c. A remote attacker can exploit this, via the escapeshellarg() PHP method, to inject arbitrary operating system commands. (CVE-2015-4642)
A heap buffer overflow condition exists in the ftp_genlist() function in ftp.c. due to improper validation of user-supplied input. A remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2015-4643)
A denial of service vulnerability exists due to a NULL pointer dereference flaw in the build_tablename() function in pgsql.c. An authenticated, remote attacker can exploit this to cause an application crash.
(CVE-2015-4644)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
