Toth Andras discovered that the fbgs framebuffer postscript/PDF viewer contains a typo, which prevents the intended filter against malicious postscript commands from working correctly. This might lead to the deletion of user data when displaying a postscript file.
For the stable distribution (sarge) this problem has been fixed in version 2.01-1.2sarge2.
For the unstable distribution (sid) this problem will be fixed soon.
We recommend that you upgrade your fbi package.
