Currently only a magazine article & draft "contents" of entire project are avaliable. Below is a slightly changed & reformatted text dump of an announcement. - --------------------------------------DUMP------------------------------------ Announce: Spaning Tree Algorithm and Protocols Familiy weakness & holes by Oleg Artemjev and Vladislav Myasnyankin The Spaning Tree Algorithm and thus - all Spaning Tree Protocols supported by lage variety of hardware vendors [lots of them provide Spaning Tree Support on their switches (commutators) & routers] contain many serious security vulnerabilities.Brief description of these vulnerabilities was published in Russian magazine "LAN" (LAN, #1 2002, more info about the magazine could be obtained from http://www.osp.ru/lan/about/). According publication conditions we can publish full matherials of our project two months later after magazine issue. Since the paper is made in Russian it will first arrive in Russian & only then, later, we'll translate it into English (do you want to help us,huh?). This announcement may be incompleet, if some differences are conflicting - the Russian version is a right source. Also note - after we'll translate the text to English it'll 1st arrive in a paper magazine. The reason is simple - we prefer to take some feedback from our research work. If you're a pubblisher (non US only! [ see LICENSE ]) - fill free to contact us (then remove "NOSPAM" before sending - it's simple antispam protection) - we're looking for an English-speaking paper magazine to publish this information before it'll be avaliable for the Internet. We already notified some vendors (Cisco, Avaya) about these vulnerabilities, but an answer was alike: "Unless this gives money we won't make investments". Well, since we're interested in high level of security in switches & routes we use, we have to publish our investigations. Because thus we 'll make some pressure on hardware vendors to implement real security in their devices. As a complain against trends to inhibit publications of security vulnerabilitties in software (these tendencies are widely known to the public as a DCMA law in U$ & judicial prosecution agains Sklyarov & Elkomsoft,also there), the announced materials will be published under following licence: - ------------------license text--------------------- License agreement.
