--- Comment #5 from Tomas Hoger <thoger@xxxxxxxxxx> ---
Here is Storable documentation that describes security risks of deserializing
untrusted inputs using Storable:
http://search.cpan.org/~ams/Storable-2.45/Storable.pm#SECURITY_WARNING

The only package shipped in Red Hat Software Collections 1 and Red Hat
Enterprise Linux 7 Beta is perl-DBI with DBI::Proxy / DBI::ProxyServer modules.
 Those modules are not used by any other package shipped as part of those
products.

There is an upstream bug requesting addition of security warnings to DBI
documentation:
https://rt.cpan.org/Public/Bug/Display.html?id=90475

It does not seem there's a way to fix without introducing incompatible protocol
change by using different way to serialize data for network transfer. 
Alternative may be to have Storable provide a safe mode to deserialize
untrusted inputs.  That seems to be on the Storable upstream TODO list, but not
available in current version.
