The + issue is not exploitable in the current Tor network because the + vulnerable code is only reached when directory authorities read bandwidth + files, but bandwidth files come from a trusted source (usually the + authorities themselves). Furthermore, the issue is only exploitable in + rare (non-POSIX) 32-bit architectures which are not used by any of the + current authorities. Fixes bug 30040; bugfix on 0.3.5.1-alpha.
