/bin/login segfaults when control-D is pressed at login: prompt. Here is the script output. Script started on Mon Jan 15 17:53:45 2001 binand@morphius[~] login login: <press control-D here> login: <again> Segmentation fault binand@morphius[~] exit Script done on Mon Jan 15 17:53:52 2001 So far as I can tell, no security issues as such, but there might be suid root programs that call /bin/login. RedHat version: 6.2 PAM version: pam-0.72-6 util-linux version: util-linux-2.10f-7 Binand
Bug verified on both 6.2 and 7. Should be fixed as of util-linux-2.10p-3 in Raw Hide.
