SAP SQL Anywhere .NET Data Provider REPLICATE Function Heap Overflow Code Execution Vulnerability

CVE ID	CVE-2014-9264
CVSS SCORE	8.5, AV:U/AC:M/Au:U/C:P/I:P/A:P
AFFECTED VENDORS	SAP
AFFECTED PRODUCTS	SQL Anywhere
VULNERABILITY DETAILS	This allows attackers to execute arbitrary code on applications which pass user provided data to the vulnerable API in SAP SQL Anywhere. The specific flaw exists within the handling of the REPLICATE function. If an application allows untrusted input to be used as the length of a REPLICATE function in a query, even if the input is correctly filtered against SQL injection, an attacker could take advantage of an arithmetic truncation error to overflow a heap buffer and execute arbitrary code in the context of the application.
ADDITIONAL DETAILS	SAP released Security Note 2057277 (http://scn.sap.com/docs/DOC-8218) to address this issue.
