In Webgalamb through 7.0, system/ajax.php functionality is supposed to be available only to the administrator. However, by using one of the bgsend, atment_sddd1xGz, or xls_bgimport query parameters, most of these methods become available to unauthenticated users.

In the Linux kernel 4.15.x through 4.19.x before 4.19.2, map_write() in kernel/user_namespace.c allows privilege escalation because it mishandles nested user namespaces with more than 5 UID or GID ranges. A user who has CAP_SYS_ADMIN in an affected user namespace can bypass access controls on resources outside the namespace, as demonstrated by reading /etc/shadow. This occurs because an ID transformation takes place properly for the namespaced-to-kernel direction but not for the kernel-to-namespaced direction.
