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 in26e89742, but it doesn't look possible to trigger until routers_make_ed_keys_unique was introduced in13a31e72. Fixes bug 19032; bugfix on tor 0.2.8.2-alpha.
Tor protects your privacy on the internet by hiding the connection
between your Internet address and the services you use. We believe Tor
is reasonably secure, but please ensure you read the instructions and
configure it properly.
