The avr_op_analyze() function in radare2 2.5.0 allows remote attackers to cause a denial of service (heap-based out-of-bounds read and application crash) via a crafted binary file.

Security readout for executives and security teams

Plain-English summary

This issue can crash radare2 2.5.0 when it analyzes a specially crafted binary file. The main business risk is denial of service in workflows that process untrusted binaries, such as malware analysis, CI scanning, or upload-based inspection services.

Executive priority

Treat as a targeted reliability risk for security tooling, not a confirmed broad enterprise compromise issue. Prioritize remediation where radare2 processes untrusted files automatically or backs customer-facing analysis services.

Technical view

CVE-2018-11377 is a heap-based out-of-bounds read in radare2 2.5.0, specifically in avr_op_analyze(). The public description ties exploitation to a crafted binary file causing application crash. The source bundle names two upstream commits and one GitHub issue, but provides no CVSS score or CWE.

Likely exposure

Exposure is most likely where radare2 2.5.0 processes third-party, uploaded, downloaded, or malware-sample binaries. Desktop-only analyst use is lower business impact than automated services where a crash interrupts processing or availability.

Exploitation context

The source states remote attackers can trigger denial of service with a crafted binary file. There is no KEV listing and no provided source evidence of active exploitation, public weaponization, privilege escalation, or code execution.

Researcher notes

Evidence is limited to the CVE description, two radare2 commits, and issue 9901. The provided data does not name a fixed release, CVSS vector, CWE, affected CPE, or exploitation in the wild.

Mitigation direction

  • Inventory systems, containers, and scripts using radare2 2.5.0.
  • Check upstream radare2 guidance and releases tied to the referenced commits.
  • Upgrade away from radare2 2.5.0 using vendor-supported packages where available.
  • Avoid processing untrusted AVR binaries with vulnerable radare2 until remediated.
  • Run binary analysis jobs in isolated, restartable worker environments.

Validation and detection

  • Confirm installed radare2 versions across analyst workstations, CI, and services.
  • Review package locks, container images, and scanner dependencies for radare2 2.5.0.
  • Confirm remediated builds include upstream fixes referenced in the CVE sources.
  • Identify public or internal upload paths that invoke radare2 analysis.
  • Test availability monitoring for analysis workers without using exploit samples.
