Vulnerability from fkie_nvd - Published: 2025-08-08 17:15 - Updated: 2025-08-08 20:30
Severity ?
3.3 (Low) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L
Summary
A vulnerability was found in libxml2 up to 2.14.5. It has been declared as problematic. This vulnerability affects the function xmlParseSGMLCatalog of the component xmlcatalog. The manipulation leads to uncontrolled recursion. Attacking locally is a requirement. The exploit has been disclosed to the public and may be used. The real existence of this vulnerability is still doubted at the moment. The code maintainer explains, that "[t]he issue can only be triggered with untrusted SGML catalogs and it makes absolutely no sense to use untrusted catalogs. I also doubt that anyone is still using SGML catalogs at all."

El responsable del c\u00f3digo explica que \u00abel problema solo puede desencadenarse con cat\u00e1logos SGML no confiables y no tiene ning\u00fan sentido usarlos. Dudo tambi\u00e9n que alguien siga utilizando cat\u00e1logos SGML\u00bb."
