Well, there is a limited number of possible hardware architectures, operating systems, and software versions. If the attacker can afford guessing, this "feature" of Pidgin is indeed useless for him. However, there are two possible uses for knowing the victim's configuration *exactly* in advance: hiding the attacker's activity and increasing the success rate of one-shot exploits (for worms).

Frankly, I don't consider this a significant information disclosure either. It's an insignificant one. :-) Most importantly, I'd like to make sure that this issue is not ignored and will be eventually fixed. -- Jabber: Client and OS version visible to authorized buddies https://bugs.launchpad.net/bugs/128159 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
