it was changed on 18 November 2015. Closes task 17906. Patch
by "teor".
o Major bugfixes (dns proxy mode, crash, backport from 0.2.8.2-alpha):
- Avoid crashing when running as a DNS proxy. Fixes bug 16248;
bugfix on 0.2.0.1-alpha. Patch from "cypherpunks".
o Minor features (bug-resistance, backport from 0.2.8.2-alpha):
- Make Tor survive errors involving connections without a
corresponding event object. Previously we'd fail with an
assertion; now we produce a log message. Related to bug 16248.
o Minor features (security, memory erasure, backport from 0.2.8.1-alpha):
- Make memwipe() do nothing when passed a NULL pointer or buffer of
zero size. Check size argument to memwipe() for underflow. Fixes
bug 18089; bugfix on 0.2.3.25 and 0.2.4.6-alpha. Reported by "gk",
patch by "teor".
o Major bugfixes (security, pointers, backport from 0.2.8.2-alpha):
- Avoid a difficult-to-trigger heap corruption attack when extending
a smartlist to contain over 16GB of pointers. Fixes bug 18162;
bugfix on 0.1.1.11-alpha, which fixed a related bug incompletely.
Reported by Guido Vranken.
o Major bugfixes (security, client, DNS proxy, backport from 0.2.8.3-alpha):
- Stop a crash that could occur when a client running with DNSPort
received a query with multiple address types, and the first
address type was not supported. Found and fixed by Scott Dial.
Fixes bug 18710; bugfix on 0.2.5.4-alpha.
- Prevent a class of security bugs caused by treating the contents
of a buffer chunk as if they were a NUL-terminated string. At
least one such bug seems to be present in all currently used
versions of Tor, and would allow an attacker to remotely crash
most Tor instances, especially those compiled with extra compiler
hardening. With this defense in place, such bugs can't crash Tor,
though we should still fix them as they occur. Closes ticket
20384 (TROVE-2016-10-001).
o Major bugfixes (parsing, security, backport from 0.2.9.8):
- Fix a bug in parsing that could cause clients to read a single
byte past the end of an allocated region. This bug could be used
