Description Robin Green 2005-04-07 17:22:27 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.6) Gecko/20050328 Firefox/1.0.2 Fedora/1.0.2-3

Description of problem:
unixODBC, at least with the postgresql driver (I haven't tried other drivers), creates insecure log files in /tmp when the debug=1 option is set in odbc.ini.

1. They contain passwords
2. They are world-readable(!)
3. Their filenames are predictable (mkstemp not used, apparently).

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

How reproducible:

Steps to Reproduce:
1. Install a program that uses ODBC.
2. Put debug=1 in /etc/odbc.ini
3. Restart the program that uses ODBC (in my case, "service ldap restart").

Actual Results:  A log file appears in /tmp, like this:

-rw-r--r--  1 ldap    ldap    197307 Apr  7 17:46 mylog_ldap14229.log

It contains the database password in the first few lines. 14229 is the pid of one of the ldap server processes (slapd), and this is not just a coincidence - log filenames are always generated from the pid.

Expected Results:  Either it should refuse to create a log file unless an explicit filename is given, or else I think it should use mkstemp (but still keep the pid in the filename for identification purposes) and set the permissions to -rw-------.

Additional info:

Not sure if this bug is in unixODBC or postgresql.
