CVE-2025-9714

Description

A flaw was found in libxstl/libxml2. The 'exsltDynMapFunction' function in libexslt/dynamic.c does not contain a recursion depth check, which may cause an infinite loop via a specially crafted XSLT document while handling 'dyn:map()', leading to stack exhaustion and a local denial of service.

Statement

No evidence was found for arbitrary memory corruption through this flaw, limiting its impact to Availability only, and reducing its severity to Moderate.

Mitigation

The impact of this flaw may be reduced by setting strict resource limits to the stack size of processes at the operational system level. This can be achieved either through the 'ulimit' shell built-in or the 'limits.conf' file.

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).
