Description |
|
|
Se ha descubierto una vulnerabilidad en las versiones anteriores a la 1.6.8 p12 de Sudo. La vulnerabilidad reside en el manejo de las variables de entorno PERLLIB, PERL5LIB y PERL5OPT. La explotación de esta vulnerabilidad podría permitir a un atacante local aumentar sus privilegios mediante la ejecución de sus propias librerías de perl a partir de scripts que se ejecuten con privilegios mediante sudo y utilicen librerías disponibles en el sistema. |
