Re: Directory traversal vulnerabilities in several archivers processing.tar

It's not always obvious that an archive shouldn't be trusted --
for example, the breakins at the BSD and Sendmail sites.

Trusting directory traversal strings (absolute paths and ../) should
require an explicit request on the part of the user. Just because a
user 'should' be wary of a trojan archive doesn't mean that they
always will be.

me" flag, you really need a lesson in 'basic' (very obvious too!)
security practices.

Powerful committed communication, reaching through fear, uncertainty and
doubt to touch the jewel within each person and bring it to life.
