SUPPORT / SAMPLES & SAS NOTES
Problem Note 68712: A stack-trace vulnerability occurs with the IMPORT procedure while importing a CSV file
 |  |  |  |  |
Severity: High
Description: In a SAS® session with the system option DBCS set, the default option for English with DBCS or UNICODE Support, PROC IMPORT might crash when importing a CSV file that contains characters that do not exist on the ANSI - Latin 1 code page. A workaround is to use a DATA step with INFILE and INPUT statements to read the delimited file.
Potential Impact: An attacker can use a resulting stack trace to gather information.
