CVE-2001-0061
FreeBSD - Privilege Escalation via procfs mem and ctl File Access
Title source: llmDescription
procfs in FreeBSD and possibly other operating systems does not properly restrict access to per-process mem and ctl files, which allows local users to gain root privileges by forking a child process and executing a privileged process from the child, while the parent retains access to the child's address space.
