Red Hat Bugzilla – Bug 152463
CAN-2005-0866 cdrecord insecure temporary file
Last modified: 2008-08-02 19:40:32 EDT
+++ This bug was initially created as a clone of Bug #152462 +++
Stolen from: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=291376
Cdrtools has some code (and default configuration) that suggests users that
want to debug its behaviour to open up a can of worms associate to insecure
temporary files usage. The Debug file defined in the configuration will
just be fopened() without any checks and is thus vulnerable to symlink
The attached patch tries to fix this minor bug (not many users will really
enabled DEBUG) by introducing a check in rscsi.c to avoid being vulnerable
to symlink attacks and by modifying the provided config file telling users
to use safe locations for debug files. The patch introduces a DoS condition
(if somebody has created the file the program will exit) and that's why
users are suggested (in the comments of the configuration file) to use a
safe location (not /tmp) for debugging.
This issue should also affect FC2
Fedora Core 3 is now maintained by the Fedora Legacy project for security
updates only. If this problem is a security issue, please reopen and
reassign to the Fedora Legacy product. If it is not a security issue and
hasn't been resolved in the current FC5 updates or in the FC6 test
release, reopen and change the version to match.
The corresponding RHEL bug was marked wontfix. Seems reasonable here too.
