[GLSA-200606-04] Tor: Several vulnerabilities

Vulnerability Assessment Summary
Tor: Several vulnerabilities

Detailed Explanation for this Vulnerability Assessment
The 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.

Impact

The possible buffer overflow may permit 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.
