CVE-1999-0120

Summary

CVE-1999-0120 is a vulnerability in Sun/Solaris systems where the writable utmp file allows local users to gain root access, bypassing the intended file permissions. This issue stems from the file not being restricted properly, leading to potential security breaches. An attacker can exploit this vulnerability by making changes to the utmp file, ultimately granting them root privileges. System administrators should ensure the utmp file is only writable by the root user to mitigate this risk.
