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 / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-misc/tor < 0.2.1.28 >= 0.2.1.28
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:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-misc/tor-0.2.1.28"
