Description:
ISS X-Force has discovered a vulnerability in various Check Point VPN-1 products, which can be exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to a boundary error in the ASN.1 decoding library during setup of the initial encrypted connection. This can be exploited to cause a heap overflow by establishing a VPN connection and sending a malicious packet containing specially crafted fields.

Successful exploitation does not require any authentication and may allow execution of arbitrary code on a vulnerable system.
