Synopsis :

The remote Gentoo host is missing one or more security-related

Description :

The remote host is affected by the vulnerability described in GLSA-200511-17
(FUSE: mtab corruption through fusermount)

Thomas Biege discovered that fusermount fails to securely handle
special characters specified in mount points.

Impact :

A local attacker could corrupt the contents of the /etc/mtab file
by mounting over a maliciously-named directory using fusermount,
potentially allowing the attacker to set unauthorized mount options.
This is possible only if fusermount is installed setuid root, which is
the default in Gentoo.

Workaround :

There is no known workaround at this time.

Solution :

All FUSE users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=sys-fs/fuse-2.4.1-r1'
