Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

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 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.
