Buffer overflow vulnerabilities in the slc_add_reply() and
|
||
|
|
env_opt_add() functions have been discovered by Gael Delalleau in the
|
||
|
|
telnet client in Heimdal.

<impact type="normal">
|
||
|
|
<p>
|
||
|
|
Successful exploitation would require a vulnerable user to connect
|
||
|
|
to an attacker-controlled host using the telnet client, potentially
|
||
|
|
executing arbitrary code with the permissions of the user running the
|
||
|
|
application.

||
|
|

|
||
|

</impact>
|
||
|
|
<workaround>
|
||
|
|
<p>
|
||
|
|
There is no known workaround at this time.
