The (1) krshd and (2) v4rcp applications in (a) MIT Kerberos 5 (krb5) up to 1.5, and 1.4.x before 1.4.4, when running on Linux and AIX, and (b) Heimdal 0.7.2 and earlier, do not check return codes for setuid calls, which allows local users to gain privileges by causing setuid to fail to drop privileges using attacks such as resource exhaustion.
