Pragma InterAccess for Microsoft 95/98 is a fully-featured commercial Telnet server.
|
|
|
|
Pragma InterAccess does not adequately compensate for large bursts of data being sent to port 23(telnet). If an excessive amount of characters(15000+) are sent to this port then the program will terminate and telnet services will shut down on that host. The daemon must be restarted to regain functionality.
|
|
|
|
This may be due to a buffer overflow condition. If this is the case, it may be possible for attackers to execute arbitrary code on the target host.
