CVE-2020-6058 — An exploitable out-of-bounds read vulnerability exists in the way MiniSNMPD version 1.4 parses incoming SNMP packets

Critical CVSS 9.1

An exploitable out-of-bounds read vulnerability exists in the way MiniSNMPD version 1.4 parses incoming SNMP packets. A specially crafted SNMP request can trigger an out-of-bounds memory read, which can result in the disclosure of sensitive information and denial of service. To trigger this vulnerability, an attacker needs to send a specially crafted packet to the vulnerable server.

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.
