FUSE

FUSE FUSE is a penetration testing system designed to identify Unrestricted Executable File Upload UEFU vulnerabilities. The details of the testing strategy is in our paper, "FUSE: Finding File Upload Bugs via Penetration Testing", which appeared in NDSS 2020. To see how to configure and execute...

kernel: fuse: re-lock request before replacing page cache folio

A flaw was found in the Linux kernel's Filesystem in Userspace FUSE component. The fusetrymovefolio function, responsible for managing page cache folios, fails to re-lock a request after initially unlocking it on a successful path. This oversight allows another function, fusechanabort, to...
