GLSA-200504-01 : telnet-bsd: Multiple buffer overflows

This script is Copyright (C) 2005-2015 Tenable Network Security, Inc.

Synopsis :

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

Description :

The remote host is affected by the vulnerability described in GLSA-200504-01
(telnet-bsd: Multiple buffer overflows)

A buffer overflow has been identified in the env_opt_add()
function of telnet-bsd, 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.

Impact :

Successful exploitation 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 telnet-bsd users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=net-misc/telnet-bsd-1.0-r1'

Risk factor :

High / CVSS Base Score : 7.5
