Problem description

Local users can use a simple C program to trigger an endless loop with floating point exceptions, thereby causing a local denial of service attack. On single processor systems, this will result in a system halt, while on SMP systems only one processor freezes with each instance of the attack.
The vulnerability is of considerably moderate severity, especially if compared to privilege escalation vulnerabilities or other vulnerabilities that do not need post-authenticated local shell access to the system like the vulnerability needs that is subject to this update. However, it is recommended to install the update on every affected system, taking into account that a local denial of service may introduce a security relevant risk to a network if exploited. Please make sure to reboot the system after successful application of the update to make the changes to the system effective.
