Hidden services should upgrade as soon as + possible; clients should upgrade whenever packages become available. + + This release also backports a simple improvement to make hidden + services a bit less vulnerable to denial-of-service attacks. + + o Major bugfixes (security, hidden service): + - Fix an issue that would allow a malicious client to trigger an + assertion failure and halt a hidden service. Fixes bug 15600; + bugfix on 0.2.1.6-alpha. Reported by "disgleirio". + - Fix a bug that could cause a client to crash with an assertion + failure when parsing a malformed hidden service descriptor. Fixes + bug 15601; bugfix on 0.2.1.5-alpha. Found by "DonnchaC". + + o Minor features (DoS-resistance, hidden service): + - Introduction points no longer allow multiple INTRODUCE1 cells to + arrive on the same circuit. This should make it more expensive for + attackers to overwhelm hidden services with introductions. + Resolves ticket 15515. + + Changes in version 0.2.4.26 - 2015-03-17 Tor 0.2.4.26 includes an updated list of directory authorities. It also backports a couple of stability and security bugfixes from 0.2.5 |
