CVE-2023-51654

Local denial of service via symlinked log file

Published Dec 26, 2023 · Updated Aug 2, 2024

Link following in Brother iPrint&Scan Desktop for Windows 11.0.0 and earlier allows local users to cause a PC denial of service. The logging component writes to a designated log path without checking whether it is a regular file or a symbolic link to another file. A low-privileged local user must create the symlink; published details establish availability loss but do not identify the overwritten target or exact failure mode.
