CVE-2002-0754

High
Published: Translated: NVD NIST

Summary

Kerberos 5 su (k5su) in FreeBSD 4.4 and earlier relies on the getlogin system call to determine if the user running k5su is root, which could allow a root-initiated process to regain its privileges after it has dropped them.

Risk Assessment

The risk is that processes may unauthorizedly regain root privileges, posing a potential security threat to the system.

Recommendation

It is recommended to upgrade to a newer version of FreeBSD that does not rely on this system call to minimize the risk associated with privilege recovery.
