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
Buffer overflow in qoslist in bos.net.tcp.server in IBM AIX 6.1 and VIOS 2.1 allows local users to gain privileges via unspecified vectors.

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

Buffer overflow vulnerability in the qoslist function of bos.net.tcp.server in IBM AIX 6.1 and VIOS 2.1 allows local authenticated users to execute arbitrary code with elevated privileges via a specially crafted input to the QoS list functionality.

MitigationApply IBM's security patch for APAR IZ69572 (or subsequent updates) to address this vulnerability, or upgrade to a patched version of AIX/VIOS as recommended by IBM.

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 the AIX or VIOS version
    Run 'oslevel -r' on AIX or 'oem_platform_level' on VIOS to determine the exact version
    Affected if The version is AIX 6.1 (6100-*) or VIOS 2.1 (2.1.*)
  2. Verify bos.net.tcp.server is installed
    Run 'lslpp -l bos.net.tcp.server' to list the installed TCP server package
    Affected if The package is installed on the system
  3. Check the bos.net.tcp.server version
    Run 'lslpp -hc bos.net.tcp.server' to get the fileset version and compare it against any known fixed versions from IBM APAR IZ69572
    Affected if The version is present and no IBM patch from APAR IZ69572 has been applied
  4. Verify QoS functionality is accessible
    Check if the 'qoslist' command or related QoS management interfaces exist by running 'which qoslist' or examining /usr/sbin for QoS-related binaries
    Affected if The qoslist command or QoS list functionality is present and executable by authenticated users

The system is affected if it is running AIX 6.1 or VIOS 2.1 with the bos.net.tcp.server package and the qoslist function is accessible without the IBM patch from APAR IZ69572 applied.
