Test Kennung:1.3.6.1.4.1.25623.1.0.52660
Kategorie:FreeBSD Local Security Checks
Titel:FreeBSD Security Advisory (FreeBSD-SA-05:01.telnet.asc)

Beschreibung:Summary:
The remote host is missing an update to the system
as announced in the referenced advisory FreeBSD-SA-05:01.telnet.asc

Vulnerability Insight:
The telnet(1) command is a TELNET protocol client, used primarily to
establish terminal sessions across a network.

Buffer overflows were discovered in the env_opt_add() and
slc_add_reply() functions of the telnet(1) command. TELNET protocol
commands, options, and data are copied from the network to a
fixed-sized buffer. In the case of env_opt_add (CVE-2005-0468), the
buffer is located on the heap. In the case of slc_add_reply
(CVE-2005-0469), the buffer is global uninitialized data (BSS).

Solution:
Upgrade your system to the appropriate stable release
or security branch dated after the correction date.
