PHP 7.0.x < 7.0.5 Multiple Vulnerabilities

critical Nessus Plugin ID 90362

Synopsis

The version of PHP on the remote web server is affected by multiple vulnerabilities.

Description

According to its banner, the version of PHP running on the remote web server is 7.0.x prior to 7.0.5. It is, therefore, affected by multiple vulnerabilities :

 - A buffer over-write condition exists in the finfo_open() function due to improper validation of magic files. An unauthenticated, remote attacker can exploit this, via a crafted file, to cause a denial of service or to execute arbitrary code.

 - A flaw exists in the php_snmp_error() function within file ext/snmp/snmp.c that is triggered when handling format string specifiers. An unauthenticated, remote attacker can exploit this, via a crafted SNMP object, to cause a denial of service or to execute arbitrary code.

 - An invalid memory write error exists when handling the path of phar file names that allows an attacker to have an unspecified impact.

 - A flaw exists in the mbfl_strcut() function within file ext/mbstring/libmbfl/mbfl/mbfilter.c when handling negative parameter values. An unauthenticated, remote attacker can exploit this to cause a denial of service.

 - An integer overflow condition exists in the php_raw_url_encode() function within file ext/standard/url.c due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this to have an unspecified impact.

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

Solution

Upgrade to PHP version 7.0.5 or later.
