Description
The issue is a stack-based buffer overflow that can be exploited by an authenticated user. This is a type of security flaw where more data is written to a buffer than it is designed to hold, which can cause the extra data to spill over into adjacent areas of memory, potentially allowing an attacker to execute arbitrary code.
