Changes in version 0.3.4.11 - 2019-02-21
- Tor 0.3.4.11 is the third stable release in its series.
+ Tor 0.3.4.11 is the third stable release in its series. It includes
+ a fix for a medium-severity security bug affecting Tor 0.3.2.1-alpha and
+ later. All Tor instances running an affected release should upgrade to
+ 0.3.3.12, 0.3.4.11, 0.3.5.8, or 0.4.0.2-alpha.
+
+ o Major bugfixes (cell scheduler, KIST, security):
+ - Make KIST consider the outbuf length when computing what it can
+ put in the outbuf. Previously, KIST acted as though the outbuf
+ were empty, which could lead to the outbuf becoming too full. It
+ is possible that an attacker could exploit this bug to cause a Tor
+ client or relay to run out of memory and crash. Fixes bug 29168;
+ bugfix on 0.3.2.1-alpha. This issue is also being tracked as
+ TROVE-2019-001 and CVE-2019-8955.
o Minor features (geoip):
- Update geoip and geoip6 to the February 5 2019 Maxmind GeoLite2
+++ /dev/null
- o Major bugfixes (cell scheduler, KIST):
- - Make KIST to always take into account the outbuf length when computing
- what we can actually put in the outbuf. This could lead to the outbuf
- being filled up and thus a possible memory DoS vector. TROVE-2019-001.
- Fixes bug 29168; bugfix on 0.3.2.1-alpha.
