CVE-2020-4433 — Certain IBM Aspera applications are vulnerable to a stack-based buffer overflow, caused by improper bounds checking

High CVSS 9.3

Certain IBM Aspera applications are vulnerable to a stack-based buffer overflow, caused by improper bounds checking. This could allow a remote attacker with intimate knowledge of the server to execute arbitrary code on the system with the privileges of root or cause server to crash. IBM X-Force ID: 180814.

Matched remediation archetype

Buffer bounds, memory safety, and memory corruption

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Identify affected native-code versions, build flags, architectures, parsers, codecs, drivers, and input paths in all shipped artifacts.
  • Determine whether untrusted data reaches the affected routine and the process privilege, sandbox, and network exposure.
  • Confirm statically linked, vendored, firmware, and platform-provided copies, not only package-manager records.

Remediate safely

  • Apply the maintained upstream correction or replace the affected component, then rebuild every dependent artifact from clean inputs.
  • Adopt bounds-checked interfaces, validated sizes and integer conversions, clear ownership, and memory-safe components where practical.
  • Enable supported compiler and runtime hardening and add sanitized tests and fuzz regression seeds derived from non-weaponized fixtures.
