Amazon Linux 2 : php (ALASPHP8.1-2025-007)

medium Nessus Plugin ID 243441

Language:

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 8.1.33-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2PHP8.1-2025-007 advisory.

 fsockopen() doesn't regard hostname as well, hostname is terminated at the null byte. This can cause Server Side Request Forgery in general case. (CVE-2025-1220)

 Missing error checking could result in SQL injection and missing error handling could lead to crashes due to null pointer dereferences. (CVE-2025-1735)

 If a SoapVar instance is created with a fully qualified name larger than 2G, this will cause a NULL pointer dereference resulting in a segmentation fault, leading to a denial of service. (CVE-2025-6491)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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.
