crypto/telnet/telnet telnet.c
usr.bin/telnet telnet.c
Log:
Correct a pair of buffer overflows in the telnet(1) command:
CAN-2005-0468) A heap buffer overflow in env_opt_add() and related
functions.
(CAN-2005-0469) A global uninitialized data section buffer overflow in
slc_add_reply() and related functions.
As a result of these vulnerabilities, it may be possible for a malicious
telnet server or active network attacker to cause telnet(1) to execute
arbitrary code with the privileges of the user running it.
These fixes are based in part on patches
