Synopsis

Description

According to its banner, the version of PHP running on the remote web server is 7.0.x prior to 7.0.13. It is, therefore, affected by multiple vulnerabilities :

- A flaw exists in the parse_url() function due to returning the incorrect host. An unauthenticated, remote attacker can exploit this to have a multiple impacts depending on how the function is implemented, which can include bypassing authentication or conducting open redirection and server-side request forgery attacks.

- An integer overflow condition exists in the _php_imap_mail() function in file ext/imap/php_imap.c when handling overly long strings. An unauthenticated, remote attacker can exploit this to cause a heap-based buffer overflow, resulting in a denial of service condition or the execution of arbitrary code.

- An integer overflow condition exists in the gdImageAALine() function within file ext/gd/libgd/gd.c due to improper validation of line limit values. An unauthenticated, remote attacker can exploit this to cause an out-of-bounds memory read or write, resulting in a denial of service condition, the disclosure of memory contents, or the execution of arbitrary code.

Note that this software is reportedly affected by other vulnerabilities as well that have not been fixed yet in version 7.0.13.
