These little exploits that occasionally pop up are a good lesson showing how using OOP and complex classes is suboptimal for secure programming. If all processes and data conversions and movements are constrained to functions with hashwall / verifier functions for each step of data or instruction transfer, exploits like this could hardly ever happen. Creating too many classes, without bootstrapping each function through a procedural verifier, you get attacks, DoSes, data breaches, etc. Exec() and eval() should be disabled on all functional filters. Pickle and modules that can evaluate code should not be used in any secure python program. All transit data should be run through encoding, conformity, hashwall, and injection filters every step of its movement. Setting up classes and objects to bounce data or pickled class code around nilly-willy is bound to break somewhere. To program securely in python one should avoid classes or libraries as far as possible. The main program functions should be sandboxed so that a second program imports and verifies them through a set of filtering functions. In short, less OOP and more functional, reflective code that is hashwall sandboxed is better for security. Bitmessage headed in this right direction by separating many functions into separate modules. However, a lot of this stuff is imported and used in stock condition, when it should be reflected through filtering functions first. These filters should perform a list of sanity and safety checks no matter what direction a data is headed. There should be flags, hashes, and a hashwall for all moving data, so the filter and recipient can check back to the hashwall for integrity. If you use python more like it is smalltalk with filters between function calls you are likely to create highly secure code.
