GLSA-200606-04 : Tor: Several vulnerabilities
Medium Nessus Plugin ID 21671
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200606-04 (Tor: Several vulnerabilities)
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.
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.
There is no known workaround at this time.
SolutionAll Tor users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose net-misc/tor
