CVE-2007-3149
Description
From CVE.org
sudo, when linked with MIT Kerberos 5 (krb5), does not properly check whether a user can currently authenticate to Kerberos, which allows local users to gain privileges, in a manner unintended by the sudo security model, via certain KRB5_ environment variable settings. NOTE: another researcher disputes this vulnerability, stating that the attacker must be "a user, who can already log into your system, and can already use sudo."
Statement
Not vulnerable. Versions of sudo package shipped with Red Hat Enterprise Linux versions 2.1, 3, 4 and 5 are linked with PAM support and never use libkrb5 authentication.
