Vulnerability Information

Severity: Critical
Vulnerability Published: 2009-06-01
Patch Published: 2010-01-27
CVE [?]: CVE-2009-1943, CVE-2009-3861
CPE [?]: cpe:/a:juniper:netscreen_remote_vpn_client

Synopsis

The remote host is affected by multiple buffer overflow vulnerabilities.

Description

The remote host is running a version of Juniper NetScreen VPN client that is affected by multiple buffer overflow vulnerabilities :

- The IKE VPN service listening on UDP port 62514 is vulnerable to a stack overflow vulnerability that can be triggered by sending specially crafted packets. (CVE-2009-1943)

- spdedit.exe has a flaw in parsing specially crafted SPD files that can be utilized to trigger a stack overflow. (CVE-2009-3861)

Successful exploitation of either of these vulnerabilities could allow a remote attacker to execute arbitrary code on the host.

Solution

Upgrade to Juniper NetScreen 9.0r5 or higher.
