Problem Note 70625: The MI procedure contains a security vulnerability when a long character variable is specified in the ADJUSTOBS= option
 |  |  |  |  |
Severity: High
Description: If UTF-8 encoding is used and a long character variable (greater than 255 bytes) is specified in the ADJUSTOBS= option in the MNAR statement, PROC MI might issue an overflow error.
To circumvent the problem, shorten the length of the variable to less than 255 bytes.
Potential Impact: The resulting overflow introduces a potential security risk.
