  o Major bugfixes (security, directory authorities):
    - Fix a crash and out-of-bounds write during authority voting, when the
      list of relays includes duplicate ed25519 identity keys. Fixes bug 19032;
      bugfix on 0.2.8.2-alpha.
Fix out-of-bounds write during voting with duplicate ed25519 keys In dirserv_compute_performance_thresholds, we allocate arrays based on the length of 'routers', a list of routerinfo_t, but loop over the nodelist. The 'routers' list may be shorter when relays were filtered by routers_make_ed_keys_unique, leading to an out-of-bounds write on directory authorities. This bug was originally introduced in 26e89742, but it doesn't look possible to trigger until routers_make_ed_keys_unique was introduced in 13a31e72. Fixes bug 19032; bugfix on tor 0.2.8.2-alpha. 2016-05-11 18:13:22 +02:00			`o Major bugfixes (security, directory authorities):`
