Changes in version 0.2.8.12 - 2016-12-19
Tor 0.2.8.12 backports a fix for a medium-severity issue (bug 21018
below) where Tor clients could crash when attempting to visit a
hostile hidden service. Clients are recommended to upgrade as packages
become available for their systems.
It also includes an updated list of fallback directories, backported
from 0.2.9.
Now that the Tor 0.2.9 series is stable, only major bugfixes will be
backported to 0.2.8 in the future.
o Major bugfixes (parsing, security, backported 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
to cause hardened clients (built with --enable-expensive-hardening)
to crash if they tried to visit a hostile hidden service. Non-
hardened clients are only affected depending on the details of
their platform's memory allocator. Fixes bug 21018; bugfix on
0.2.0.8-alpha. Found by using libFuzzer. Also tracked as TROVE-
2016-12-002 and as CVE-2016-1254.
o Minor features (fallback directory list, backported from 0.2.9.8):
- Replace the 81 remaining fallbacks of the 100 originally
introduced in Tor 0.2.8.3-alpha in March 2016, with a list of 177
fallbacks (123 new, 54 existing, 27 removed) generated in December
2016. Resolves ticket 20170.
o Minor features (geoip, backported from 0.2.9.7-rc):
- Update geoip and geoip6 to the December 7 2016 Maxmind GeoLite2
Country database.
Changes in version 0.2.8.11 - 2016-12-08
