[GLSA-200503-36] netkit-telnetd: Buffer overflow Vulnerability Scan
Vulnerability Scan Summary
netkit-telnetd: Buffer overflow
Detailed Explanation for this Vulnerability Test
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.
Successful explotation would require a vulnerable user to connect
to a possible hacker-controlled host using telnet, potentially executing
arbitrary code with the permissions of the telnet user.
There is no known workaround at this time.
All netkit-telnetd users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/netkit-telnetd-0.17-r6"
Threat Level: Medium
