CVE-2020-13493
Description
A heap overflow vulnerability exists in Pixar OpenUSD 20.05 when the software parses compressed sections in binary USD files. A specially crafted USDC file format path jumps decompression heap overflow in a way path jumps are processed. To trigger this vulnerability, the victim needs to open an attacker-provided malformed file.
AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
Heap overflow in Pixar OpenUSD 20.05 when parsing compressed binary USD files allows remote code execution via a crafted file.
Vulnerability
A heap overflow vulnerability exists in Pixar OpenUSD version 20.05 when parsing compressed sections of binary USD files. Specifically, the overflow occurs during decompression of the PATHS section (CVE-2020-13493). The bug is in the way path jumps are processed in compressed data [1].
Exploitation
An attacker can exploit this vulnerability by crafting a malicious USDC file and convincing a victim to open it. No authentication or special network position is required; the victim only needs to open the file using an application that uses OpenUSD, such as macOS Quick Look (which automatically renders thumbnails) or an iOS app that processes USD files [1].
Impact
Successful exploitation allows an attacker to achieve remote code execution with the privileges of the user opening the file. The vulnerability has high impact on confidentiality, integrity, and availability [1].
Mitigation
No official fix is specified in the available reference [1]. Users are advised to update to a version of OpenUSD later than 20.05 if available, or to avoid opening untrusted USD files.
