Bugzilla: 916075: CVE-2013-1772 kernel: call_console_drivers() function log prefix stripping DoS


The MITRE CVE dictionary describes this issue as:

The log_prefix function in kernel/printk.c in the Linux kernel 3.x before 3.4.33 does not properly remove a prefix string from a syslog header, which allows local users to cause a denial of service (buffer overflow and system crash) by leveraging /dev/kmsg write access and triggering a call_console_drivers function call.
