CWE-119  (opens in a new tab)

How to fix?

Upgrade tor to version 0.2.1.30 or higher.

Overview

Affected versions of this package are vulnerable to Out-of-Bounds. Buffer overflow in the policy_summarize function in or/policies.c in Tor before 0.2.1.30 allows remote attackers to cause a denial of service (directory authority crash) via a crafted policy that triggers creation of a long port list.
