Description Agostino Sarubbo gentoo-dev 2013-03-11 11:28:40 UTC
From ${URL} :

It was reported [1] that busybox creates part of the /dev directory tree with incorrect permissions 
when creating device nodes in nested directories.  This has been fixed [2] upstream.

1.20.2 is vulnerable, but 1.21.0 not, after checking if the commit was in the sources

Thanks for checking. 

Should we proceed to stabilize 1.21.0?

CVE-2013-1813 (
  util-linux/mdev.c in BusyBox before 1.21.0 uses 0777 permissions for parent
  directories when creating nested directories under /dev/, which allows local
  users to have unknown impact and attack vectors.
