Gentoo Linux Security Advisory
Title: Tor: Remote heap-based buffer overflow (GLSA 201101-02)
Severity: high
Exploitable: remote
Date: January 15, 2011
Bug(s): #349312
ID: 201101-02
Synopsis
Tor is vulnerable to a heap-based buffer overflow that may allow arbitrary
code execution.
Background
Tor is an implementation of second generation Onion Routing, a
connection-oriented anonymizing communication service.
Affected Packages
Package: net-misc/tor
Vulnerable: < 0.2.1.28
Unaffected: >= 0.2.1.28
Architectures: All supported architectures
Description
Tor contains a heap-based buffer overflow in the processing of user or
attacker supplied data. No additional information is available.
Impact
Successful exploitation of this vulnerability may allow an
unauthenticated remote attacker to execute arbitrary code with the
permissions of the Tor user, or to cause a Denial of Service.
Workaround
There is no known workaround at this time.
Resolution
All Tor users should upgrade to the latest stable version:
Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/tor-0.2.1.28" |
