Hello Debain Users,
We have an interesting phenomenon occuring on one
of our servers. We have noticed that two files in the /bin directory have had
their executable permissions removed and we are unable to chmod the files as
root.
current file permissions:
-rw-r--r-- 1
root root
35464 May 31 13:02 /bin/login
-rw-r--r-- 1
root root
54152 Aug 29 2001 /bin/netstat
when trying to change permissions:
ns:~# whoami
root ns:~# id
uid=0(root) gid=0(root) groups=0(root) ns:~# chmod 755 /bin/login
chmod: changing permissions of `/bin/login': Operation not permitted We have tried doing the same thing from the rescue
disc login prompt. same outcome.
This seems to be a serious security issue. Root
user seems to have lost control of some files. Other files can be changed using
the above commands.
Any ideas?
Best regards,
Andreas Hatz
