CVE-2007-3149 Information

Description

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.\
