CVE-2025-1219
Description
A flaw was found in PHP's DOM and SimpleXML extensions. This vulnerability allows incorrect parsing of a redirected HTTP resource via improper content-type header handling.
Statement
Moderate impact: Red Hat Enterprise Linux is affected by a PHP flaw in the DOM and SimpleXML extensions. When an application requests an HTTP resource that performs a redirect, the wrong Content-Type header is used to determine the character set, which can cause the resulting document to be parsed incorrectly or allow validations to be bypassed. The affected RHEL entries include streams with delegated resolution, for which a fix is being pursued; RHEL entries marked not affected remain outside the affected scope. Red Hat In-Vehicle OS entries are affected with resolution deferred, so the residual risk is that redirected HTTP resources processed by DOM or SimpleXML may still be parsed incorrectly or bypass validations. Fedora 40 and Fedora 41 are not affected because inline mitigations already exist. Red Hat rates the issue Low (CVSS 3.7) rather than the external Moderate ratings because its assessment assigns high attack complexity and limited confidentiality impact.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)
Availability
Technical Impact: DoS: Crash, Exit, or Restart; DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory)
An attacker could provide unexpected values and cause a program crash or arbitrary control of resource allocation, leading to excessive consumption of resources such as memory and CPU.
Confidentiality
Technical Impact: Read Memory; Read Files or Directories
An attacker could read confidential data if they are able to control resource references.
Integrity,Confidentiality,Availability
Technical Impact: Modify Memory; Execute Unauthorized Code or Commands
An attacker could use malicious input to modify data or possibly alter control flow in unexpected ways, including arbitrary command execution.
