Descriptions

qmail-verify as used in netqmail 1.06 is prone to an information disclosure vulnerability. A local attacker can test for the existence of files and directories anywhere in the filesystem because qmail-verify runs as root and tests for the existence of files in the attacker's home directory, without dropping its privileges first.

qmail-verify como es usado en netqmail versión 1.06, es propenso a una vulnerabilidad de divulgación de información. Un atacante local puede probar la existencia de archivos y directorios en cualquier parte del sistema de archivos porque qmail-verified es ejecutado como root y prueba la existencia de archivos en el directorio de inicio del atacante, sin perder sus privilegios primero.
