Hi,

I just checked the patch that Debian proposes; this is the relevant part:

--- p3nfs-5.19.orig/etc/bluetooth.rc
+++ p3nfs-5.19/etc/bluetooth.rc
@@ -14,7 +14,8 @@
 
 prog="bluetooth"
 ROOT=/local/bluez-2.0
-exec >> /tmp/blue.log 2>&1
+TMPFILE=$(mktemp -t blueXXXXXXXXX || exit 1)
+exec >> $TMPFILE 2>&1
 
 echo "--------------------"
 echo "$*"

The vulnerable part that is being patched is a bluetooth subsystem start/stop script that is not even installed by our ebuild.

This is a resolved:INVALID to me...

ack, closing as invalid then.
