Exploit públicoDisponiblePublicado en Exploit-DB

Un desbordamiento de búfer en la función intTT1_EnvGetCompletePath en el archivo lib/t1lib/t1env.c en t1lib versión 5.1.1, permite a atacantes dependiendo del contexto ejecutar código arbitrario por medio de un parámetro FileName largo. NOTA: este problema se reportó originalmente de estar en la función imagepsloadfont en la biblioteca php_gd2.dll en la extensión gd (PHP_GD2) en PHP versión 5.2.3.

CVSS

Puntuación base: 7.5
Versión: 2.0
Vector: AV:N/AC:L/Au:N/C:P/I:P/A:P

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 19 %
Percentil entre todas las CVEs puntuadas: 97
Fecha de la puntuación: 21/10/2026

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
