Summary

Linux version 2.0.34 does not properly prevent users from sending SIGIO signals to arbitrary processes, allowing local users to cause a denial of service by sending SIGIO to processes that do not catch it.

Risk Assessment

Local users can disrupt system operation, leading to denial of service for other users or applications.

Recommendation

It is recommended to update the system to a newer kernel version that improves SIGIO signal handling and restricts their sending by unauthorized users.
