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 an attempt to exploit a buffer overflow vulnerability in Csound.
Csound is a sound and music composition application.
Csound is prone to multiple buffer-overflow vulnerabilities because it fails to properly bounds check user-supplied data:
1. A stack-based buffer-overflow in the 'getnum()' function of the 'util/heti_main.c' source file. This issue occurs when handling a specially-crafted hetro file.
2. A stack-based buffer-overflow in the 'getnum()' function of the 'util/pv_import.c' source file. This issue occurs when handling a specially-crafted PVOC file.
An attacker can exploit these issues to execute arbitrary code within the context of the affected application. Failed attacks will cause denial-of-service conditions.
