Subject: Announce: modutils 2.3.20 is available

Due to the recent modutils 2.3 local root exploits, anybody using
modutils 2.3 should upgrade to 2.3.20. That means everybody using 2.4
kernels.

The security patch to modutils 2.3.19 only closed part of the exploit,
this version should close all known exploits. modutils still supports
meta expansion, including back quoted commands, but only for data read
from the configuration file. This assumes that when modutils is run as
root out of the kernel, normal users cannot specify their own
configuration files.
