-----BEGIN PGP SIGNED MESSAGE----- nternet Security Systems Protection Brief July 28, 2004
Check Point VPN-1 ASN.1 Decoding Remote Compromise Summary: ISS has shipped protection for a flaw X-Force has discovered in CheckPoint VPN-1 Server. The Check Point VPN-1 product is widely relied upon to provide secure remote access to private networks from less trusted network environments. When establishing an encrypted connection to a virtual private network (VPN), it is possible for an attacker to trigger a buffer overflow vulnerability in an ASN.1 decoding library within the VPN-1 product. Note: The vulnerability described in this advisory is distinct and separate frompreviously announced issues and customers are advised to assess their protection accordingly. Business Impact: Compromise of VPN-1 networks may lead to exposure of confidential information, loss of productivity, and further network compromise. Successful exploitation of this vulnerability could be used to gain unauthorized access to networks being protected by Check Point�s VPN-1 product. No authentication would be required for an attacker to leverage this vulnerability to compromise a VPN, and operational VPN-1 installations will likely be vulnerable in their default configurations.
