CVE-2005-4532

High
Published: Translated: NVD NIST

Summary

A vulnerability in scponlyc (scponly 4.1 and earlier) allows a local user to execute arbitrary code with root privileges by creating a chroot directory in their home directory, hard linking to a system setuid application, and using a modified LD_PRELOAD to alter expected function calls in the setuid application.

Risk Assessment

A local user can gain full root access to the system, compromising confidentiality, integrity, and availability of data and services.

Recommendation

Immediately upgrade scponly to version 4.2 or later, which fixes this vulnerability, and consider disabling the LD_PRELOAD mechanism for setuid applications.
