CVE-2025-32799

  2. Vulnerabilities (CVE)
  3. CVE-2025-32799
Conda-build contains commands and tools to build conda packages. Prior to version 25.4.0, the conda-build processing logic is vulnerable to path traversal (Tarslip) attacks due to improper sanitization of tar entry paths. Attackers can craft tar archives containing entries with directory traversal sequences to write files outside the intended extraction directory. This could lead to arbitrary file overwrites, privilege escalation, or code execution if sensitive locations are targeted. This issue has been patched in version 25.4.0.

Summary
  • (es) Conda-build contiene comandos y herramientas para compilar paquetes conda. En versiones anteriores a la 25.4.0, la lógica de procesamiento de conda-build era vulnerable a ataques de path traversal (Tarslip) debido a una limpieza incorrecta de las rutas de entrada tar. Los atacantes pueden manipular archivos tar con entradas con secuencias de directory traversal para escribir archivos fuera del directorio de extracción previsto. Esto podría provocar sobrescrituras arbitrarias de archivos, escalada de privilegios o ejecución de código si se atacan ubicaciones sensibles. Este problema se ha corregido en la versión 25.4.0.
