Hewlett-Packard Company will not be liable for any consequences to any customer resulting from customer's failure to fully implement instructions in this Security Bulletin as soon as possible. ------------------------------------------------------------------------- PROBLEM: The Million Question vulnerability affects the use of RSA Data Security encryption algorithms with Netscape server products that support Secure Sockets Layer (SSL). The nature of the vulnerability is that a single encrypted SSL network conversation could be recorded and subsequently decrypted. The Netscape Enterprise Server Release 2.01 is embedded in the VirtualVault A.02.00 and A.03.00 releases. PLATFORM: HP9000 Series 7/800 running: HP-UX 10.24 (VVOS) with VirtualVault A.02.00 (NES 2.01 embedded) HP-UX 10.24 (VVOS) with VirtualVault A.03.00 (NES 2.01 embedded) DAMAGE: A cryptanalytic vulnerability could potentially be used to discover the key for a particular encrypted session through a process of repeatedly sending on the order of one million carefully constructed messages to a target server and observing the server's response. SOLUTION: Apply the appropriate VirtualVault Patch noted below. AVAILABILITY: All patches for the VirtualVault releases 2.0 and 3.0 are available now from HP. ------------------------------------------------------------------------- I. A. Background According to RSA Data Security, Inc., this potential attack against secure Web communications is currently the subject of research and has not been reported by any users. CERT has made a technical advisory (CA-98.07.PKCS) on this vulnerability available at http://www.cert.org/. B. Recommended solution This problem can be eliminated by installing the recommended patch. Hewlett-Packard recommends that the following patches be loaded as applicable: HP-UX 10.24 (VVOS) with VirtualVault A.02.00 (US/Canada): PHSS_15993 HP-UX 10.24 (VVOS) with VirtualVault A.02.00 (Export): PHSS_15994 HP-UX 10.24 (VVOS) with VirtualVault A.03.00 (US/Canada): PHSS_15935 HP-UX 10.24 (VVOS) with VirtualVault A.03.00 (Export): PHSS_15936 Customers running the Export version of VirtualVault (B5410AA, B5410BA, B5412AA, B5412BA) may download the patch PHSS_15994 or PHSS_15936 from the Electronic Support Center or request a tape from their local Response Center. Customers running the US/Canada version of VirtualVault (B5409AA, B5409BA, B5411AA, B5411BA) who reside in the US or Canada can request a tape of patch PHSS_15993 or PHSS_15935 from their local Response Center. Customers running the US/Canada version of VirtualVault outside of the US and Canada will be shipped the patch directly. C. Impact of the patch Applying patches PHSS_15993, PHSS_15994, PHSS_15935 or PHSS_15936 eliminates the vulnerability in the Netscape Enterprise Server yet does not otherwise impact the system. D.
