Description:

The remote host is affected by the vulnerability described in GLSA-200503-36
(netkit-telnetd: Buffer overflow)


A buffer overflow has been identified in the slc_add_reply()
function of netkit-telnetd client, where a large number of SLC commands
can overflow a fixed size buffer.

Impact

Successful explotation would require a vulnerable user to connect
to an attacker-controlled host using telnet, potentially executing
arbitrary code with the permissions of the telnet user.

Workaround

There is no known workaround at this time.

Solution:
All netkit-telnetd users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/netkit-telnetd-0.17-r6"


Risk factor : Medium
