From $URL : Description A vulnerability has been reported in Linux Kernel, which can be exploited by malicious, local users to cause a DoS (Denial of Service). The vulnerability is caused due to an error in the "call_console_drivers()" function (kernel/printk.c) when stripping log prefixes. This can be exploited to cause the system to stop responding via specially crafted shell commands. The vulnerability is reported in versions prior to 3.0.66, 3.2.38, and 3.4.33. Solution Update to version 3.0.66, 3.2.38, or 3.4.33.
