CVE-2013-1772  (opens in a new tab)
CWE-119  (opens in a new tab)

How to fix?

Upgrade torvalds/linux to version 3.4.33 or higher.

Overview

Affected versions of this package are vulnerable to Out-of-Bounds. 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.
