Changes in version 0.3.5.16 - 2021-08-16
- This version fixes several bugs from earlier versions.
+ This version fixes several bugs from earlier versions of Tor, including one
+ that could lead to a denial-of-service attack. Everyone running an earlier
+ version, whether as a client, a relay, or an onion service, should upgrade
+ to Tor 0.3.5.16, 0.4.5.10, or 0.4.6.7.
+
+ o Major bugfixes (cryptography, security):
+ - Resolve an assertion failure caused by a behavior mismatch between
+ our batch-signature verification code and our single-signature
+ verification code. This assertion failure could be triggered
+ remotely, leading to a denial of service attack. We fix this issue
+ by disabling batch verification. Fixes bug 40078; bugfix on
+ 0.2.6.1-alpha. This issue is also tracked as TROVE-2021-007 and
+ CVE-2021-38385. Found by Henry de Valence.
o Minor feature (fallbackdir):
- Regenerate fallback directories list. Close ticket 40447.
