A proof of concept exploit for a time-of-check to time-of-use local privilege escalation vulnerability in libcap version 2.77. The vulnerability exists in capsetfile, which checks a supplied pathname with lstat before independently resolving the same pathname when calling setxattr. Because setxat...

GHSA-945V-V9P3-V5XW rclone local `--metadata` applies attacker-controlled mode/uid - setuid binary planted from an untrusted remote

Summary When writing an object with metadata, the local backend applies the source-supplied mode, uid, and gid verbatim: it parses mode as an octal integer and passes it straight into os.Chmodo.path, os.FileModeumode, and passes uid/gid straight into os.Chown. The value is never masked to...
