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

medium Tenable Cloud Security Plugin ID 476626

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,
 some functions, including urldecode(), pass signed char to ctype functions (like isxdigit()). On the
 systems with default signed char and optimized table-lookup ctype functions - such as NetBSD - this can
 lead to accessing array with negative offset, which can trigger a denial of service. (CVE-2026-7258)

Solution

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