"The developers of Tor the internet anonymisation system, have announced that thanks to a Coverity analysis, they have removed a number of bugs and vulnerabilities. Coverity perform source code analysis of C, C++ and Java and in September 2008, found 171 problems in the Tor code base. By December 2008, the Tor developers had got the count down to 15 issues, and have now managed to reduce the bug count to 0.

In announcing that they were Down to 0 issues on Coverity Scan, the developers said that using Coverity’s free of charge programme for scanning open source software for vulnerabilities had identified many issues which were "just sloppiness in our unit tests’ error handling", but that number of the discovered issues were real bugs.

I’ve recently installed Vidalia/Tor/Privoxy/Torbutton and it seems to be working great but it has covertly disabled the network firewall portion of a Zone Alarm Pro v8 installation which had been working fine (perfectly, as best I could tell w/o a packet sniffer). The PC’s behind a router so unsolicited incoming traffic is not a problem, and programs still ask for permission to access the ‘net, but any filters/rules to block outgoing access to certain domains or IP addresses or IP ranges are now ignored as if they don’t even exist (I can still edit them but it has no effect).

Also, ZApro8’s log seems to have gotten wiped: it’s still seemingly all there on disk, but the ZA program will not display any alerts of any kind prior to when Vidalia/Tor/Privoxy were installed.

It certainly appears that the latest version of Vidalia + Tor + Privoxy has at least partially clobbered the 2nd-latest version of Zone Alarm ( The release notes for the newer version do not mention anything related to this issue, so I’m not sure it even makes sense to try giving (a newer) ZA a chance to clobber Tor now.
