### Summary A Use-After-Free (UAF) vulnerability has been discovered in the Sdf_PathNode module of the Pixar OpenUSD library. This issue occurs during the deletion of the Sdf_PrimPathNode object in multi-threaded environments, where freed memory is accessed. This results in segmentation faults or bus errors, allowing attackers to potentially exploit the vulnerability for remote code execution (RCE). By using a specially crafted .usd file, an attacker could gain control of the affected system. The vulnerability has been confirmed in multiple OpenUSD tools, including sdfdump, usdtree, usdcat, and sdffilter. ### Patches This is fixed with [commit 0d74f31](https://github.com/PixarAnimationStudios/OpenUSD/commit/0d74f31fe64310791e274e587c9926335e9db9db), with the fix available in OpenUSD 25.08 and onwards. ### Details The issue is a Use-After-Free vulnerability in the Sdf_PathNode destruction process, specifically in Sdf_PrimPathNode::~Sdf_PrimPathNode(). When multiple threads attempt to...

Cybersecurity today is less about single attacks and more about chains of small weaknesses that connect into big risks. One overlooked update, one misused account, or one hidden tool in the wrong hands can be enough to open the door. The news this week shows how attackers are mixing methods—combining stolen access, unpatched software, and clever tricks to move from small entry points to large

Sending AWS chunk data with no Content-Length HTTP header causes the panic, every time. ### Reproduction Setup versity server running on port 7071, no SSL (for ease of packet tracing with tshark). Problem can be reproduced with or without SSL on the versity end. Use nginx to reverse proxy on port 7070. This does have to be SSL enabled for the repro to occur. nginx config: ``` upstream tony_versity { server 127.0.0.1:7071; keepalive 15; } server { listen 7070 ssl ; access_log /var/log/nginx/tony_versity_proxy.access.log; error_log /var/log/nginx/tony_versity_proxy.error.log; # Allow any size file to be uploaded. client_max_body_size 0; # Allow special characters in headers ignore_invalid_headers off; # Disable buffering proxy_buffering off; proxy_request_buffering off; # Load configuration files for the default server block. include /etc/nginx/default.d/*.conf; ssl_certificate "/WS/TEMP/lh.crt"; ss...

Organizations looking to better understand the lineage of their software artifacts have begun to adopt signing as a way to improve their security posture. By applying digital signatures to software artifacts, trust can be established to verify that assets have not been substituted or tampered with through the software development and delivery process.Red Hat Trusted Artifact Signer, a key component of Red Hat’s Trusted Software Supply Chain portfolio, provides a suite of tools that supports signing and verifying assets from first commit to deployment. Since Trusted Artifact Signer was first
