CVE-2013-4419 Information

Description

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.
