The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-200504-04
(mit-krb5: Multiple buffer overflows in telnet client)
A buffer overflow has been identified in the env_opt_add()
function, where a response requiring excessive escaping can cause a
heap-based buffer overflow. Another issue has been identified in the
slc_add_reply() function, where a large number of SLC commands can
overflow a fixed size buffer.
Successful exploitation would require a vulnerable user to connect
to an attacker-controlled telnet host, potentially executing arbitrary
code with the permissions of the telnet user on the client.
There is no known workaround at this time.
