The remote host is affected by the vulnerability described in GLSA-201309-21
(klibc: Command Injection)
The ipconfig utility in klibc writes DHCP options to
/tmp/net-$DEVICE.conf, and this file is later sourced by other scripts to
get defined variables. The options written to this file are not properly
A remote attacker could send a specially crafted DHCP reply, which could
execute arbitrary shell code with the privileges of any process which
sources DHCP options.
There is no known workaround at this time.
