CVE-2006-3084

High
Published: Translated: NVD NIST

Summary

A vulnerability in the ftpd and ksu programs in MIT Kerberos 5 (up to 1.5, and 1.4.x before 1.4.4) and Heimdal (0.7.2 and earlier) fails to check return codes for setuid calls. This might allow local users to gain privileges by causing setuid to fail to drop privileges. As of 20060808, it is not known whether an exploitable attack scenario exists.

Risk Assessment

A local user could potentially gain elevated privileges, leading to a breach of confidentiality, integrity, and availability. However, the risk is limited because no exploitable attack scenario has been confirmed.

Recommendation

Update MIT Kerberos 5 to version 1.4.4 or later (or 1.5) and Heimdal to a version newer than 0.7.2. If updating is not possible, consider disabling or restricting access to the ftpd and ksu services.
