Upgrade Echo:latest inetutils to version 2:2.4-2+deb12u3 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream inetutils package and not the inetutils package as distributed by Echo.
See How to fix? for Echo:latest relevant fixed versions and status.
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.
