RHEL 10 : php8.4 (RHSA-2026:87071)

critical Nessus Plugin ID 370216

Synopsis

The remote Red Hat host is missing one or more security updates for php8.4.

Description

The remote Redhat Enterprise Linux 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:87071 advisory.

PHP is an HTML-embedded scripting language. PHP attempts to make it easy for developers to write dynamically generated web pages. PHP also offers built-in database integration for several commercial and non-commercial database management systems, so writing a database-enabled webpage with PHP is fairly simple. The most common use of PHP coding is probably as a replacement for CGI scripts.

Security Fix(es):

* php: php: Denial of Service via unbounded recursion in SOAP parser (CVE-2026-91765)

* php: OOM bailout during request parsing leads to memory corruption and RCE (CVE-2026-109618)

* php: fatal error handling retains stale request state leading to use-after-free (CVE-2026-109619)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux 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

Update the RHEL php8.4 package based on the guidance in RHSA-2026:87071.
