[GLSA-200511-17] FUSE: mtab corruption through fusermount |
||
FUSE: mtab corruption through fusermount Detailed Explanation for this Vulnerability Assessment 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 permiting 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.
