CVE-2013-1772

Status Candidate

Overview

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.

Red Hat Security Advisory 2013-0566-01
Posted Mar 7, 2013
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2013-0566-01 - The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. A buffer overflow flaw was found in the way UTF-8 characters were converted to UTF-16 in the utf8s_to_utf16s() function of the Linux kernel's FAT file system implementation. A local user able to mount a FAT file system with the "utf8=1" option could use this flaw to crash the system or, potentially, to escalate their privileges.
