user can delete kernel images
Hi,
Something very strange has happened to my system. I have my kernels in
/boot (the usual setup ) with permission 644. I have never touched that
after they are created by the kernel-package. I am doing some experiments
concerning security. So I tried as a user with no root privileges and no
root group privileges to delete the files /boot/vmlinuz.2.0.0 and
/boot/vmlinuz.2.0.27 I was asked whether 644 should be overrided I said
yes and it removed the files !!!! Why ?? This is of no immediate risk
since I have several more kernels which I use but this is scary. Can
anayone explain this ??
Thanks
George
