|Gentoo Linux Security Advisory
Title: Tor: Remote heap-based buffer overflow (GLSA 201101-02)
Date: January 15, 2011
Tor is vulnerable to a heap-based buffer overflow that may allow arbitrary
Tor is an implementation of second generation Onion Routing, a
connection-oriented anonymizing communication service.
Vulnerable: < 0.2.1.28
Unaffected: >= 0.2.1.28
Architectures: All supported architectures
Tor contains a heap-based buffer overflow in the processing of user or
attacker supplied data. No additional information is available.
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.
There is no known workaround at this time.
All Tor users should upgrade to the latest stable version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/tor-0.2.1.28"
