APP: PoPToP 'poptop-sane.c' Buffer Overflow
This signature detects attempts to exploit a known vulnerability in Poptop PPTP Server for Linux. Poptop 1.0.1 and earlier versions are vulnerable. A successful attack can lead to a buffer overflow and arbitrary remote code execution within the context of logged-in user.
Extended Description
A buffer-overflow vulnerability has been discovered in PoPToP PPTP. The problem occurs because the software fails to do sufficient sanity checks when referencing user-supplied input used in various calculations. As a result, an attacker may be able to trigger a condition that would corrupt sensitive memory. Successful exploits of this issue may allow attackers to execute arbitrary code with the privileges of the affected server.
