-Description: Be compliant with POS36-C: Observe correct revocation order while relinquishing privileges
-Author: Orion Poplawski <orion@cora.nwra.com>
-Abstract:
- The Fedora review of NX (redistributed) caught the following rpmlint issue:
- .
- This executable is calling setuid and setgid without setgroups or initgroups.
- There is a high probability this mean it didn't relinquish all groups, and this
- would be a potential security issue to be fixed. Seek POS36-C on the web for
- details about the problem.
- .
- Ref POS36-C:
- https://www.securecoding.cert.org/confluence/display/seccode/POS36-C.+Observe+correct+revocation+order+while+relinquishing+privileges
- .
- This patch adds initgroups() calls to the code to initialize the supplemental group list.
