Synopsis ========
Tor is vulnerable to a possible buffer overflow, a Denial of Service, information disclosure and information leak.
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 < 0.1.1.20 >= 0.1.1.20
Description ===========
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.
Resolution ==========
All Tor users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-misc/tor-0.1.1.20"
