Description |
|
|
Se ha descubierto una vulnerabilidad en sperl, el "wrapper" utilizado por Perl para ejecutar programas setuid. La vulnerabilidad reside en que un usuario puede especificar en que archivo se guardará la información de debug que genera un script en perl mediante la variable de entorno PERLIO_DEBUG. La explotación de esta vulnerabilidad podría permitir a un atacante local sobrescribir archivos del sistema con privilegios de root. |
