Sudo 1.6.8p7 on SuSE Linux 9.3, and possibly other Linux distributions, allows local users to gain privileges by using sudo to call su, then entering a blank password and hitting CTRL-C. NOTE: SuSE and multiple third-party researchers have not been able to replicate this issue, stating "Sudo catches SIGINT and returns an empty string for the password so I don't see how this could happen unless the user's actual password was empty.

sudo 1.6.0 through 1.6.3p7 does not properly clear the environment before calling the mail program, which could allow local users to gain root privileges by modifying environment variables and changing how the mail program is invoked.

Sudo 1.5 in Debian Linux 2.1 and Red Hat 6.0 allows local users to determine the existence of arbitrary files by attempting to execute the target filename as a program, which generates a different error message when the file does not exist.
