Subject: Stop leaking information across requests
X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?p=catagits%2Ffcgi2.git;a=commitdiff_plain;h=297693dc8362d25bb25e473899c72508a0f71d2e
Stop leaking information across requests
%hash is false if the hash hasn't been assigned to, *or* if the hash is simply
empty. This causes the environment from the *second* request (that is, the
environment produced by the first request) to be saved as default if the first
request had empty environment. This way, request after the first can get access
to credentials set up by the first request.
Instead of fixing this, I'd much rather remove this old and buggy
interface. However, 10 years of deprecation don't seem to have been enough for
CGI::Fast to switch to the new and properly supported interface. :-(
This is CVE-2011-2766.
