I see no effect on RAM (there > seems to be a limit) but heavy cpu. <snip> Right. I quickly read your message, and assumed this was an issue of recursively-packed files. I see now that you're talking about 'new' bzip2 bombs (recently also discussed on Full-Disclosure and other lists). To be perfectly honest, I don't think Sophie is supposed to take care of this issue. Either Sophos (in their lib) or ulimits on the system should worry about such issues, and I don't see a way Sophie could prevent this issue. Any suggestions are, of course, more than welcome :) Thanks. Vanja
