NETWORK Attack complexity
LOW Privileges required
NONE Confidentiality impact
PARTIAL Integrity impact
NONE Availability impact
NONE Summary
Tor before 0.1.1.20 allows remote attackers to identify hidden services via a malicious Tor server that attempts a large number of accesses of the hidden service, which eventually causes a circuit to be built through the malicious server.

NASL family Gentoo Local Security Checks NASL id GENTOO_GLSA-200606-04.NASL description The remote host is affected by the vulnerability described in GLSA-200606-04 (Tor: Several vulnerabilities) Some integer overflows exist when adding elements to the smartlists. Non-printable characters received from the network are not properly sanitised before being logged. There are additional unspecified bugs in the directory server and in the internal circuits. Impact : The possible buffer overflow may allow a remote attacker to execute arbitrary code on the server by sending large inputs. The other vulnerabilities can lead to a Denial of Service, a lack of logged information, or some information disclosure. Workaround : There is no known workaround at this time. last seen 2020-06-01 modified 2020-06-02 plugin id 21671 published 2006-06-08 reporter This script is Copyright (C) 2006-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/21671 title GLSA-200606-04 : Tor: Several vulnerabilities code #%NASL_MIN_LEVEL 80502 # # (C) Tenable Network Security, Inc. # # The descriptive text and package checks in this plugin were # extracted from Gentoo Linux Security Advisory GLSA 200606-04. # # The advisory text is Copyright (C) 2001-2018 Gentoo Foundation, Inc. # and licensed under the Creative Commons - Attribution / Share Alike # license.
