Overview
Affected versions of this package are vulnerable to Symlink Attack via the handling of ancillary file writes such as --log-file, --write-batch, or daemon-mode log and statistics paths. An attacker can overwrite arbitrary files by placing a symlink at a predictable output path and redirecting output to arbitrary filesystem locations. This can lead to local privilege escalation if the process runs with elevated privileges such as setuid or as a privileged daemon. This is only exploitable if the process is executed with elevated privileges.
