SUSE CVE-2015-3202

fusermount in FUSE before 2.9.3-15 does not properly clear the environment before invoking 1 mount or 2 umount as root, which allows local users to write to arbitrary files via a crafted LIBMOUNTMTAB environment variable that is used by mount's debugging feature...

SUSE CVE-2015-8785

The fusefillwritepages function in fs/fuse/file.c in the Linux kernel before 4.4 allows local users to cause a denial of service infinite loop via a writev system call that triggers a zero length for the first segment of an iov...

SUSE CVE-2016-1233

An unspecified udev rule in the Debian fuse package in jessie before 2.9.3-15+deb8u2, in stretch before 2.9.5-1, and in sid before 2.9.5-1 sets world-writable permissions for the /dev/cuse character device, which allows local users to gain privileges via a character device in /dev, related to an...

SUSE CVE-2016-1576

The overlayfs implementation in the Linux kernel through 4.5.2 does not properly restrict the mount namespace, which allows local users to gain privileges by mounting an overlayfs filesystem on top of a FUSE filesystem, and then executing a crafted setuid program...

SUSE CVE-2016-2853

The aufs module for the Linux kernel 3.x and 4.x does not properly restrict the mount namespace, which allows local users to gain privileges by mounting an aufs filesystem on top of a FUSE filesystem, and then executing a crafted setuid program...

SUSE CVE-2017-15121

A non-privileged user is able to mount a fuse filesystem on RHEL 6 or 7 and crash a system if an application punches a hole in a file that does not end aligned to a page boundary...

SUSE CVE-2018-1120

A flaw was found affecting the Linux kernel before version 4.17. By mmaping a FUSE-backed file onto a process's memory containing command line arguments or environment strings, an attacker can cause utilities from psutils or procps such as ps, w or any other program which makes a read call to the...

SUSE CVE-2018-10906

In fuse before versions 2.9.8 and 3.x before 3.2.5, fusermount is vulnerable to a restriction bypass when SELinux is active. This allows non-root users to mount a FUSE file system with the 'allowother' mount option regardless of whether 'userallowother' is set in the fuse configuration. An attack...

SUSE CVE-2019-11487

The Linux kernel before 5.1-rc5 allows page-refcount reference count overflow, with resultant use-after-free issues, if about 140 GiB of RAM exists. This is related to fs/fuse/dev.c, fs/pipe.c, fs/splice.c, include/linux/mm.h, include/linux/pipefsi.h, kernel/trace/trace.c, mm/gup.c, and...

SUSE CVE-2019-20794

An issue was discovered in the Linux kernel 4.18 through 5.6.11 when unprivileged user namespaces are allowed. A user can create their own PID namespace, and mount a FUSE filesystem. Upon interaction with this FUSE filesystem, if the userspace component is terminated via a kill of the PID...

SUSE CVE-2020-10744

An incomplete fix was found for the fix of the flaw CVE-2020-1733 ansible: insecure temporary directory when running becomeuser from become directive. The provided fix is insufficient to prevent the race condition on systems using ACLs and FUSE filesystems. Ansible Engine 2.7.18, 2.8.12, and 2.9....

SUSE CVE-2020-36322

An issue was discovered in the FUSE filesystem implementation in the Linux kernel before 5.10.6, aka CID-5d069dbe8aaf. fusedogetattr calls makebadinode in inappropriate situations, causing a system crash. NOTE: the original fix for this vulnerability was incomplete, and its incompleteness is...

SUSE CVE-2020-36394

pamsetquota.c in the pamsetquota module before 2020-05-29 for Linux-PAM allows local attackers to set their quota on an arbitrary filesystem, in certain situations where the attacker's home directory is a FUSE filesystem mounted under /home...

SUSE CVE-2021-3995

A logic error was found in the libmount library of util-linux in the function that allows an unprivileged user to unmount a FUSE filesystem. This flaw allows an unprivileged local attacker to unmount FUSE filesystems that belong to certain other users who have a UID that is a prefix of the UID of...

SUSE CVE-2022-30783

An invalid return code in fusekernmount enables intercepting of libfuse-lite protocol traffic between NTFS-3G and the kernel in NTFS-3G through 2021.8.22 when using libfuse-lite...

SUSE CVE-2022-30785

A file handle created in fuselibopendir, and later used in fuselibreaddir, enables arbitrary memory read and write operations in NTFS-3G through 2021.8.22 when using libfuse-lite...

SUSE CVE-2022-30787

An integer underflow in fuselibreaddir enables arbitrary memory read operations in NTFS-3G through 2021.8.22 when using libfuse-lite...
