Descriptions
transports/appendfile.c in Exim before 4.72, when a world-writable sticky-bit mail directory is used, does not verify the st_nlink field of mailbox files, which allows local users to cause a denial of service or possibly gain privileges by creating a hard link to another user's file.
transports/appendfile.c en Exim antes de v4.72, cuando se usa un directorio de correo con permisos de escritura para todos y sticky-bit activado, no verifica el campo de st_nlink de los ficheros de buzón de correo, que permite a usuarios locales causar una denegación de servicio o posiblemente obtener privilegios mediante la creación de un vínculo físico a un archivo de otro usuario.
Multiple vulnerabilities were found in Exim, the worst of which leading to remote execution of arbitrary code with root privileges. Versions less than 4.80.1 are affected.
