Steps to Reproduce: 1. as root user, run echo ":text:E::txt::/cat.txt:" > /proc/sys/fs/binfmt_misc/register; touch /cat.txt; chmod +x /cat.txt 2) as normal user, run /cat.txt I can confirm that this reproducible on rhel3. However, it doesn't rise to the level of critical bugfix, given that root-owned files must be mis-configured. |
