During the optimizer run, it creates debug output file with pre-defined name: /tmp/hugin_debug_optim_results.txt . If file was already created by other user, hugin gives an error message. This problem can be abused by malicious local user to perform symlink attack against user running hugin, which will result in overwrite of arbitrary file writable by user running hugin with panorama optimizer output. There does not seem to be any upstream patch at the moment. Updated package was released for openSuSE, which resolves this problem by disabling creation of debug file.

The fix however is a simple one-liner: sed -i 's/define DEBUG_WRITE_OPTIM_OUTPUT$/undef DEBUG_WRITE_OPTIM_OUTPUT/' \ src/Panorama/PTOptimise.cpp Though currently hugin isn't buildable for either f7 or f8 due to #295521 so this one is stucked.

However, upstream may want to develop other fix, which does not sacrifice some functionality (I'm not trying to say fix above is wrong ;). According to comments in huginApp.cpp, there is some intention to fix temp file usage: // FIXME, make secure against some symlink attacks Reply at: https://bugs.launchpad.net/ubuntu/+source/hugin/+bug/162602/comments/2 ------------------------------------------------------------------------ On 2007-10-24T20:00:11+00:00 Bruno wrote: Created attachment 236541 Patch to fix CVE-2007-5200 This is the upstream patch to fix this and another similar bug.

Huh, I even forgot about that :) Anyways, as you can see, the package built. That can mean that either some other build root change (gcc or whatever) solved that or it is really specific to your configuration. Which version do you run, are you completly up-to-date?
