Use of Uninitialized Memory in pybddisasm Python Bindings

Publication date: 2026-11-03

Last updated on: 2026-11-03

Assigner: Bitdefender

Description
A use of uninitialized memory vulnerability in the pybddisasm Python bindings affects nd_to_text. If the underlying text conversion fails, including failures caused by invalid parameters, the output buffer may remain uninitialized while still being converted into a Python return value. This may disclose residual process memory or cause the Python process to crash. Exploitation requires an application to invoke nd_to_text in a way that causes conversion to fail and to return or otherwise use the resulting output. The pybddisasm package is no longer maintained.

Executive Summary

This vulnerability involves a use of uninitialized memory in the pybddisasm Python bindings, specifically in the nd_to_text function. When text conversion fails due to invalid parameters, the output buffer may remain uninitialized but still be returned as a Python value. This can expose residual process memory or crash the Python process.

Impact Analysis

An attacker could exploit this by causing nd_to_text to fail and return uninitialized memory, potentially leaking sensitive data or crashing the application. This requires the application to use nd_to_text in a way that triggers conversion failure.

Mitigation Strategies

Immediately stop using the pybddisasm package as it is no longer maintained and contains a critical uninitialized memory vulnerability. Replace it with an actively maintained alternative for text conversion tasks.
