CVE-2025-9714

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.

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

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

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.
