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 Novell iPrint Client before 5.44 allows remote attackers to execute arbitrary code via a long call-back-url parameter in an op-client-interface-version action.

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 · high confidence

Stack-based buffer overflow vulnerability in Novell iPrint Client versions prior to 5.44 allows remote attackers to execute arbitrary code by sending an excessively long call-back-url parameter within an op-client-interface-version action. The overflow occurs on the stack, enabling potential complete system compromise.

MitigationUpgrade Novell iPrint Client to version 5.44 or later. Until patched, restrict network access to untrusted iPrint servers and disable the iPrint browser plugin for untrusted sites.

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. Check if Novell iPrint Client is installed
    On Windows: Check Program Files for 'Novell' or 'iPrint' folder, or look in Add/Remove Programs. On Linux: Check for rpm packages with 'iprint' in the name using 'rpm -qa | grep -i iprint'. On Mac: Check /Applications for iPrint related apps.
    Affected if Novell iPrint Client software is found on the system
  2. Determine the installed iPrint Client version
    Windows: Look in Add/Remove Programs for the version number, or check the DLL version in the iPrint installation directory. Linux: Run 'rpm -qa | grep -i iprint' to list installed packages with versions.
    Affected if The installed version matches any of these: 4.26, 4.27, 4.28, 4.30, 4.32, 4.34, 4.36, 4.38, 5.04, 5.12, 5.20b, or any version 5.42 or lower, OR if the exact version cannot be determined but iPrint Client is present and has not been updated since 2010
  3. Verify if iPrint browser plugin is enabled
    Check browser add-ons or extensions: In Internet Explorer go to Manage Add-ons. In Firefox check Add-ons > Plugins. In Chrome check Extensions. Look for 'Novell iPrint' or 'iPrint' plugin entries.
    Affected if The iPrint browser plugin is enabled and active in any web browser on the system
  4. Inspect network exposure to iPrint servers
    Review browser proxy settings and firewall rules that allow connections to port 631 (IPP) or custom iPrint server ports. Check if the system is configured to automatically connect to iPrint servers.
    Affected if The system is configured to connect to untrusted or external iPrint servers without restriction

A user is affected if Novell iPrint Client is installed with a version less than 5.44 (specifically any of the listed affected versions or <=5.42) AND the browser plugin is enabled, allowing a malicious server to send the overflow payload via the call-back-url parameter.

Upgrade available Upgrade to a release after 5.42
Interim mitigation

Upgrade Novell iPrint Client to version 5.44 or later. Until patched, restrict network access to untrusted iPrint servers and disable the iPrint browser plugin for untrusted sites.

Recommended fix High confidence

Novell iPrint Client 5.44 or later

  1. Obtain Novell iPrint Client version 5.44 or later from official Novell/SUSE channels
  2. Uninstall the existing Novell iPrint Client version
  3. Install the upgraded version 5.44 or later
  4. Verify the installation by checking the client version through the iPrint interface
