CVE-1999-0820

Summary

CVE-1999-0820 is a vulnerability affecting FreeBSD's seyon utility. This issue enables users to manipulate the PATH variable, allowing them to execute commands with elevated privileges. Instead of finding the intended xterm and seyon-emu commands from their standard locations, users can specify alternative paths, leading to unintended and potentially harmful executable files being invoked. This can result in serious security consequences, as unauthorized users may be able to gain administrative access to the system.
