Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Stack-based buffer overflow in capture in IBM AIX 5.3 SP6 and 5.2.0 allows remote attackers to execute arbitrary code via a large number of terminal control sequences.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

Stack-based buffer overflow vulnerability in the 'capture' utility on IBM AIX 5.3 SP6 and 5.2.0 allows remote attackers to execute arbitrary code by sending a large number of terminal control sequences. The overflow occurs on the stack, enabling attackers to overwrite return addresses and inject malicious code.

MitigationUpgrade AIX to a supported version receiving security patches, or if upgrade is not feasible, restrict network access to the capture utility and implement compensating controls such as firewall rules limiting exposure to trusted networks.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify AIX version
    Run 'oslevel -s' or 'oslevel' command to determine the installed AIX version
    Affected if Version is exactly 5.2.0 or any 5.3.x release (including 5.3 SP6)
  2. Locate the capture utility
    Run 'which capture' or 'lslpp -l | grep -i capture' to find if the capture utility is installed
    Affected if The capture utility binary exists on the system
  3. Verify capture utility is executable
    Check file permissions with 'ls -la /usr/bin/capture' or similar path, and verify the binary has executable permissions
    Affected if The capture utility has executable permissions for users who could trigger the overflow
  4. Assess network exposure
    Review network access controls, firewall rules, or TCP wrappers configuration that may allow remote access to the capture utility. Check if the utility listens on any network port by reviewing /etc/services and running 'netstat -an | grep capture' if applicable
    Affected if The capture utility is network-accessible from untrusted hosts

The system is affected if it runs AIX 5.2.0 or 5.3.x AND has the capture utility installed and exposed, allowing remote attackers to send terminal control sequences to trigger the stack-based buffer overflow.

Mitigation

Upgrade AIX to a supported version receiving security patches, or if upgrade is not feasible, restrict network access to the capture utility and implement compensating controls such as firewall rules limiting exposure to trusted networks.
