Comment 4 Eugene Teo (Security Response) 2009-06-26 09:42:57 UTC

This commit includes a bugfix for the fragile setuid fixup code in the case that filesystem capabilities are supported (in access()).  The effect of this fix is gated on filesystem capability support because changing securebits is only supported when filesystem capabilities support is configured.)
