Oracle iPlanet Web Proxy Server 4.0.x < 4.0.27 NSS ASN.1 Decoder RCE (April 2016 CPU)

High Nessus Plugin ID 90627


The remote web proxy server is affected by a remote code execution vulnerability.


According to its self-reported version, the Oracle iPlanet Web Proxy Server (formerly known as Sun Java System Web Proxy Server) installed on the remote host is version 4.0.x prior to 4.0.27. It is, therefore, affected by a heap buffer overflow condition in the ASN.1 decoder in the Network Security Services (NSS) library. A remote attacker can exploit this, via crafted OCTET STRING data, to cause a denial of service or to execute arbitrary code.


Upgrade to Oracle iPlanet Web Proxy Server version 4.0.27 or later as referenced in the April 2016 Oracle Critical Patch Update advisory.
