CVE-2010-3879
Description
From CVE.org
FUSE, possibly 2.8.5 and earlier, allows local users to create mtab entries with arbitrary pathnames, and consequently unmount any filesystem, via a symlink attack on the parent directory of the mountpoint of a FUSE filesystem, a different vulnerability than CVE-2010-0789.
Statement
The Red Hat Security Response Team has rated this issue as having low security impact. On Red Hat Enterprise Linux 5 and 6, a user must be a member of the 'fuse' group in order to use FUSE. Due to the risks associated with fixing this bug on Red Hat Enterprise Linux 5, and because of the group restrictions in place, we currently have no plans to fix this flaw in Red Hat Enterprise Linux 5.
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).
