"It was discovered that there was an insecure default PATH in dietlibc,
a libc optimized for small size.

Thorsten Glaser discovered that the default PATH in dietlibc (if the
environment variable is unset) contained the current working
directory.

For Debian 7 'Wheezy', this issue has been fixed in :

  - dietlibc version 0.33~cvs20120325-4+deb7u1

  - minit version 0.10-5+deb7u1

We recommend that you upgrade your dietlibc and minit packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
