Bugzilla: 1016960: CVE-2013-4419 libguestfs: insecure temporary directory handling for guestfish's network socket


The MITRE CVE dictionary describes this issue as:

The guestfish command in libguestfs 1.20.12, 1.22.7, and earlier, when using the --remote or --listen option, does not properly check the ownership of /tmp/.guestfish-$UID/ when creating a temporary socket file in this directory, which allows local users to write to the socket and execute arbitrary commands by creating /tmp/.guestfish-$UID/ in advance.
