Package: libice6 Version: 2:1.0.6-1 Severity: normal libice creates UNIX sockets which names includes the pid of the creating process: | $ netstat -len 2>/dev/null | grep ICE | unix 2 [ ACC ] STREAM LISTENING 7460 @/tmp/.ICE-unix/2389 | unix 2 [ ACC ] STREAM LISTENING 7461 /tmp/.ICE-unix/2389
The pid value as seen by the process itself via getpid(2) on Linux is not longer unique if pid namespaces or the process freezer are in use. Also other processes may see a different pid for it. Please use some more random for creating this socket names, as they are communicated via a environment variable (SESSION_MANAGER) anyway. My current project is a kiosk multiseat system. Every seat runs within its own mount namespace (so it have a completely seperated filesystem) and pid namespace (so it can't see any processes outside). But as every seat is setup the same way and no network namespaces are in use, the x session manager gets the same pid and the ICE socket name is already taken.
