Name of the Vulnerable Software and Affected Versions lib60870-C version 2.4.0
Description A heap-based buffer overflow occurs in the server-side FileSegment ASDU encoding path. The issue arises because the FileSegment encode() function validates only the standalone segment length using FileSegment GetMaxDataSize() and fails to verify the residual capacity of the current ASDU frame before encoding object fields and segment data.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
