CGIWrap before 3.10 allows remote attackers to obtain sensitive information via unknown attack vectors that cause errors in scripts that reveal system information.

The CGIwrap program before 3.9 on Debian GNU/Linux uses an incorrect minimum value of 100 for a UID to determine whether it can perform a seteuid operation, which could allow attackers to execute code as other system UIDs that are greater than the minimum value, which should be 1000 on Debian systems.
