Echo: php-8.1: security update to 8.1.34+e1

medium Tenable Self-Hosted Container Security Plugin ID 476633

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In PHP versions 8.2.* before 8.2.31, 8.3.* before 8.3.31, 8.4.* before 8.4.21, and 8.5.* before 8.5.6, the
metaphone() function in ext/standard/metaphone.c uses a signed int variable to track the current position
within the input string. If a string longer than 2,147,483,647 bytes is passed, a signed integer overflow
occurs, resulting in undefined behavior. This can lead to an out-of-bounds read, causing a segmentation
fault or access to unrelated memory, and may affect the availability of the PHP process. (CVE-2026-7568)

Solution

Update the php-8.1 library and its related packages to version 8.1.34+e1 or later.
