This attack could pose a serious security threat. You should take immediate action to stop any damage or prevent further damage from happening.
This signature detects attempts to exploit a buffer overflow vulnerability in CoolPDF Reader which may result in remote code execution.
CoolPDF is a PDF reader application.
The application is prone to a remote buffer-overflow vulnerability because it fails to perform adequate checks on user-supplied input. Specifically, this issue occurs when processing a specially crafted stream in a PDF file.
Successfully exploiting this issue may allow remote attackers to execute arbitrary code in the context of the application. Failed attacks will cause denial-of-service conditions.
- CoolPDF 220.127.116.116 is vulnerable; other versions may also be affected.
