[GLSA-200511-17] FUSE: mtab corruption through fusermount Vulnerability Scan
Vulnerability Scan Summary
FUSE: mtab corruption through fusermount
Detailed Explanation for this Vulnerability Test
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.

# emerge --sync

Threat Level: Medium
