Time to go digging … One aspect of that bug is in a pipeline, for eventual reporting to the developer of the antivirus software. Another aspect of the bug is outlined in the file overview.txt at <http://www.wuala.com/grahamperrin/public/2010/11/09/c? mode=gallery> -- AFAICT there is, at least, a bug in the documentation of the security model of TrueCrypt; and I have reported this bug through the normal channel. In a nutshell: * as volumes mounted by TrueCrypt, and files thereon, are accessible to all other users of the system, so I assume that TrueCrypt is using one of the following options for MacFUSE: allow_other allow_root * permissions for one user's volumes are by default ignored when another user logs on to the system, so the setting of permissions (advised in the documentation for TrueCrypt) is ineffective. ---- This post is simply a placeholder. A point of reference for anyone who encounters the issue from the perspective of antivirus software, or from the perspective of TrueCrypt, *wondering* whether their installed version of MacFUSE is contributory to the issue. I do **not** suspect an issue with MacFUSE -- the bug reproduces whilst using the antivirus software on both (a) a PowerPC with MacFUSE 2.1.5 (Beta) AFAIR from Google Code, and (b) my MacBook Pro with the 2010-10-20 Tuxera distribution of macfuse-core-10.5-2.1.9.dmg -- You received this message because you are subscribed to the Google Groups "MacFUSE" group.
