Description Martin Prpič 2015-02-23 16:09:16 UTC
A flaw was found in the method that the linux kernel handles userspace tuning of the Reliable Datagram Sockets (RDS) system settings. The incorrect handling allowed a trusted user to set multiple RDS sysctls for RDS with specially formatted data.  Reading from these files also returned data from other sysctl settings that would be exposed via the same permissions to this user.

This bug provides little risk to users as the values that can be modified are exposed via proc sysctls with the same permissions.
