Tor 0.1.2.15 fixes several crash bugs, fixes some anonymity-related problems, fixes compilation on BSD, and fixes a variety of other bugs. Everybody should upgrade. https://tor.eff.org/download.html Changes in version 0.1.2.15 - 2007-07-17 o Major bugfixes (compilation): - Fix compile on FreeBSD/NetBSD/OpenBSD. Oops. o Major bugfixes (crashes): - Try even harder not to dereference the first character after an mmap(). Reported by lodger. - Fix a crash bug in directory authorities when we re-number the routerlist while inserting a new router. - When the cached-routers file is an even multiple of the page size, don't run off the end and crash. (Fixes bug 455; based on idea from croup.) - Fix eventdns.c behavior on Solaris: It is critical to include orconfig.h _before_ sys/types.h, so that we can get the expected definition of _FILE_OFFSET_BITS. o Major bugfixes (security): - Fix a possible buffer overrun when using BSD natd support. Bug found by croup. - When sending destroy cells from a circuit's origin, don't include the reason for tearing down the circuit. The spec says we didn't, and now we actually don't. Reported by lodger. - Keep streamids from different exits on a circuit separate. This bug may have allowed other routers on a given circuit to inject cells into streams. Reported by lodger; fixes bug 446. - If there's a never-before-connected-to guard node in our list, never choose any guards past it. This way we don't expand our guard list unless we need to. o Minor bugfixes (guard nodes): - Weight guard selection by bandwidth, so that low-bandwidth nodes don't get overused as guards. o Minor bugfixes (directory): - Correctly count the number of authorities that recommend each version. Previously, we were under-counting by 1. - Fix a potential crash bug when we load many server descriptors at once and some of them make others of them obsolete. Fixes bug 458. o Minor bugfixes (hidden services): - Stop tearing down the whole circuit when the user asks for a connection to a port that the hidden service didn't configure. Resolves bug 444. o Minor bugfixes (misc): - On Windows, we were preventing other processes from reading cached-routers while Tor was running. Reported by janbar. - Fix a possible (but very unlikely) bug in picking routers by bandwidth. Add a log message to confirm that it is in fact unlikely. Patch from lodger. - Backport a couple of memory leak fixes. - Backport miscellaneous cosmetic bugfixes.
