Amazon Linux 2 : php (ALASPHP8.0-2023-006)

high Nessus Plugin ID 181389

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of php installed on the remote host is prior to 8.0.20-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2PHP8.0-2023-006 advisory.

- In PHP versions 7.4.x below 7.4.30, 8.0.x below 8.0.20, and 8.1.x below 8.1.7, when using Postgres database extension, supplying invalid parameters to the parametrized query may lead to PHP attempting to free memory using uninitialized data as pointers. This could lead to RCE vulnerability or denial of service. (CVE-2022-31625)

- In PHP versions 7.4.x below 7.4.30, 8.0.x below 8.0.20, and 8.1.x below 8.1.7, when pdo_mysql extension with mysqlnd driver, if the third party is allowed to supply host to connect to and the password for the connection, password of excessive length can trigger a buffer overflow in PHP, which can lead to a remote code execution vulnerability. (CVE-2022-31626)

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

Solution

Run 'yum update php' to update your system.
