Description P Fudd 2005-07-27 10:26:03 UTC

Description of problem:
According to the man page, 'touch /tftpboot/somefile; chmod 666
/tftpboot/somefile' should allow you to 'put somefile' using tftp.

Version-Release number of selected component (if applicable):
tftp-server-0.40-6

How reproducible:
Always

Steps to Reproduce:
1. Enable tftpd (chkconfig tftp on; service xinetd restart)
2. touch /tftpboot/somefile; chmod 666 /tftpboot/somefile
3. tftp localhost
4. put /etc/issue somefile
  
Actual results:
File not found

Expected results:
Contents should be put successfully

Additional info:
Problem is in server, not client.
strace bombs with buffer overflow error when tracing tftpd.

The steps above work for me with SELinux turned off. When I turn on the SELinux
with `setenforce 1` the file is not uploaded with "Permission denied" error. Can
you please retest this issue with SELinux turned off? (eg. add `setenforce 0`
before your testcase)
