Description of problem:
The release of perl in rawhide does not support perl-suidperl.
BackupPC is the last remaining package which requires perl-suidperl.
It therefore shows up as package with broken deps in rawhide package deps reports, e.g.
i.e. this package is not installable under rawhide
Version-Release number of selected component (if applicable):
This package will have to be removed from
Fedora >=14, should this issue not be resolved.
One simple option would be to create a C wrapper for BackupPC_Admin script and make that setuid instead of the script itself.
See http://perldoc.perl.org/perlsec.html#Security-Bugs for more details.
I've mailed upstream about that issue:
There's also a debian bug about the same issue, but little progress.
Using a C wrapper is really quite simple. Move the existing BackupPC_Admin script to BackupPC_Admin.pl, compile the wrapper and install as /usr/share/BackupPC/sbin/BackupPC_Admin with permissions 4755.
#define REAL_PATH "/usr/share/BackupPC/sbin/BackupPC_Admin.pl"
int main(ac, av)
Thank for the tip Iain :)
I will probably use that to fix the current issue (I really do not want to see BackupPC disappear from repositories).
I won't have tiome for that until next week (I'm very overbooked this week), I hope having some advices from upstream until that.
Someone on BackupPC users mailing list tell me I can use apache suid mechanism (http://sourceforge.net/mailarchive/forum.php?thread_name=4C2F62D4.3010702%40gmail.com&forum_name=backuppc-users).
What do you think about this solution?
Unfortunately, I don't think you'll be able to use apache's suexec mechanism. It's configured at compile time to only execute programs that live under /var/www (and packaging guidelines forbids packages from installing anything under /var/www), and to only execute programs as a user with uid >= 500 and gid >= 100.
This bug appears to have been reported against 'rawhide' during the Fedora 14 development cycle.
Changing version to '14'.
