SUPPORT / SAMPLES & SAS NOTES
Problem Note 69591: The MI procedure contains a stack-corruption vulnerability when specifying certain generalized logit models
 |  |  |  |  |
Severity: High
Description: If you specify the LOGISTIC(LINK=GLOGIT) option in the FCS statement or the MONOTONE statement, PROC MI might issue the following error:
ERROR: An exception has been encountered.
Please contact technical support and provide them with the following traceback information:
The SAS task name is [MI ]
Segmentation Violation
Please contact technical support and provide them with the following traceback information:
The SAS task name is [MI ]
Segmentation Violation
This error can occur when the imputed variable contains many levels and the model cannot be estimated. This problem has been observed when the imputed variable contains more than five or six levels.
The only workaround is to use PROC DISCRIM instead, although this might be more statistically valid than attempting to fit a generalized logit model with a large number of levels.
Potential Impact: The resulting segmentation violation introduces a potential security risk.
