Gentoo Linux Security Advisory
Title: Tor: Denial of Service (GLSA 201507-02)
Severity: normal
Exploitable: remote
Date: July 06, 2015
Bug(s): #545940
ID: 201507-02
Synopsis
Two vulnerabilities have been found in Tor, the worst of which can
allow remote attackers to cause a Denial of Service condition.
Background
Tor is an implementation of second generation Onion Routing, a
connection-oriented anonymizing communication service.
Affected Packages
Package: net-misc/tor
Vulnerable: < 0.2.6.7
Unaffected: >= 0.2.6.7
Architectures: All supported architectures
Description
Tor does not handle data correctly when specifically crafted data is
sent, and also fails to properly verify a descriptor provided by a hidden
service directory.
Impact
A remote attacker could cause a Denial of Service condition in both a
Tor client or a Tor server.
Workaround
There is no known workaround at this time.
Resolution
All Tor users should upgrade to the latest version: Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/tor-0.2.6.7"
|
