Description Ronald Cole 2004-10-12 01:23:33 UTC
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; 
SV1; .NET CLR 1.0.3705; .NET CLR 1.1.4322)

Description of problem:
$ uucp -C fi_uir.asc t17007!~/               
uucp: stat (/home/bms/tmp/rjc/fi_uir.asc): Permission denied

... which is a misleading error message since strace indicates that 
uucp is unable to open /var/spool/uucp/t17007/SEQF:

$ ls -l /var/spool/uucp/t17007/SEQF 
-rw-------    1 uucp     uucp            4 Oct 12 
10:01 /var/spool/uucp/t17007/SEQF

strace indicates that the reason it can't is because uucp seems to
not have the uucp uid at that point (it has mine instead).  But uucp 
is definitely suid:

$ ls -l /usr/bin/uucp
-r-sr-xr-x    1 uucp     uucp      1305254 Jan 25  2003 /usr/bin/uucp

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. try to "uucp -C" a file from your system to another system

Actual Results:  uucp failed with an error message and the copy 
didn't happen.

Expected Results:  uucp copies the file to the spool directory and 
then transfers the file to the remote system.

Created attachment 105031 [details]
output of "strace uucp -C fi_uir.asc t17007!~/

notice the return values to the get*uid*() calls.  I can't tell how uucp lost
it's suid during program execution from this output, but it apparently did.

Comment 2 Peter Vrabec 2004-11-19 13:16:10 UTC
this helps me

- user must be in uucp group
- chmod g+w /var/spool/uucppublic
