This buffer underflow vulnerability occurs because the length of a header line is stored in a signed integer, which can lead to integer wraparound for very large inputs. This results in pointer underflow and out-of-bounds memory access. Exploitation requires a local user to install or process a specially crafted treemagic file, which can lead to local denial of service or application instability."}, {"lang": "es", "value": "Se encontr\u00f3 una falla en la l\u00f3gica de an\u00e1lisis de tipos de contenido de Glib. Esta vulnerabilidad de desbordamiento negativo de b\u00fafer ocurre porque la longitud de una l\u00ednea de encabezado se almacena en un entero con signo, lo que puede llevar a un desbordamiento de entero para entradas muy grandes. Esto resulta en un desbordamiento negativo de puntero y acceso a memoria fuera de l\u00edmites. La explotaci\u00f3n requiere que un usuario local instale o procese un archivo treemagic especialmente dise\u00f1ado, lo que puede llevar a una denegaci\u00f3n de servicio local o inestabilidad de la aplicaci\u00f3n."}], "lastModified": "2026-03-18T17:16:05.690", "sourceIdentifier": "secalert@redhat.com"}
