CVE-2013-4419

Description

From CVE.org

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.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
