PHP 7.4.x < 7.4.18 / 8.x < 8.0.5 Integer Overflow

high Nessus Plugin ID 149348

Language:

Synopsis

The version of PHP running on the remote web server is affected by an integer overflow condition.

Description

The version of PHP installed on the remote host is 7.4.x prior to 7.4.18, or 8.x prior to 8.0.5. It is, therefore, affected by an integer overflow condition in pnctl_exec(). An attacker can exploit this to cause a denial of service (DoS) condition or the execution of arbitrary code.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version

Solution

Upgrade to PHP version 7.4.18, 8.0.5 or later.
