2.1

Low

Base vector

AV:L/AC:L/Au:N/C:N/I:P/A:N

Name of the Vulnerable Software and Affected Versions FUSE versions prior to 2.4.1

Description The issue allows local users to corrupt /etc/mtab and possibly modify mount options by performing a mount over a directory whose name contains certain special characters. This can lead to a violation of protected information integrity. The exploitation of this issue can be carried out locally.

Recommendations For versions prior to 2.4.1, update to version 2.4.1 or later to resolve the issue. As a temporary workaround, consider removing the setuid root bit from fusermount to prevent local users from exploiting this issue. Restrict access to fusermount to minimize the risk of exploitation.
