telnetd in GNU inetutils through 2.7 allows an out-of-bounds write in the LINEMODE SLC (Set Local Characters) suboption handler because add_slc does not check whether the buffer is full.

This Telnet flaw could be exploited by an unauthenticated attacker to achieve code execution. Immediate patching is strongly recommended.
