Description Agostino Sarubbo gentoo-dev 2013-11-25 19:49:15 UTC
From ${URL} :

Linux kernel built with a Gigabit Ethernet device support(CONFIG_QETH) is
vulnerable to a buffer overflow flaw. It could occur while doing an
ioctl(SIOC_QETH_ADP_SET_SNMP_CONTROL) call.

A user/program could use this flaw to crash the kernel resulting in DoS or 
potentially escalate user privileges on a system.

CVE-2013-6381 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-6381):
  Buffer overflow in the qeth_snmp_command function in
  drivers/s390/net/qeth_core_main.c in the Linux kernel through 3.12.1 allows
  local users to cause a denial of service or possibly have unspecified other
  impact via an SNMP ioctl call with a length value that is incompatible with
  the command-buffer size.
