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
Heap-based buffer overflow in nipplib.dll in Novell iPrint Client before 5.78 on Windows allows remote attackers to execute arbitrary code via a crafted client-file-name parameter in a printer-url, a different vulnerability than CVE-2011-1705.

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

Heap-based buffer overflow in nipplib.dll in Novell iPrint Client versions before 5.78 on Windows allows remote attackers to execute arbitrary code via a crafted client-file-name parameter in a printer URL.

MitigationUpgrade Novell iPrint Client to version 5.78 or later; if immediate patching is not feasible, restrict network access to trusted print servers and disable iPrint client functionality where not required.

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. Verify Novell iPrint Client installation
    Check for the presence of the iPrint client application or nipplib.dll on the system. Common locations include: C:\Program Files\Novell\iPrint\ or search for nipplib.dll using file search.
    Affected if Novell iPrint Client is installed and the file nipplib.dll exists on the system
  2. Determine installed iPrint Client version
    Right-click on nipplib.dll in the iPrint installation directory, select Properties, then view the Details tab for version information. Alternatively, check Add/Remove Programs for the Novell iPrint Client entry and its version.
    Affected if The installed version matches one of the affected versions: 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 5.74 and below
  3. Confirm nipplib.dll file version
    If the main iPrint Client version is unclear, right-click on the nipplib.dll file directly and check the File Version in the Version tab. Compare this against the affected version list.
    Affected if The nipplib.dll file version corresponds to a vulnerable iPrint Client version listed in the affected versions
  4. Check if iPrint client browser integration is active
    Examine browser add-ons or check if the iPrint extension is loaded in web browsers (Internet Explorer, Firefox). Also verify if iPrint is configured as the default printer handler.
    Affected if The iPrint client is actively integrated with the system and capable of processing printer URLs from remote servers

A system is affected if Novell iPrint Client is installed with nipplib.dll present and the version matches any of the vulnerable versions (4.26 through 5.74 inclusive, or specifically 5.20b, 5.12, 5.04, 4.38, 4.36, 4.34, 4.32, 4.30, 4.28, 4.27, or 4.26).

Upgrade available Upgrade to a release after 5.74
Interim mitigation

Upgrade Novell iPrint Client to version 5.78 or later; if immediate patching is not feasible, restrict network access to trusted print servers and disable iPrint client functionality where not required.

Recommended fix High confidence

5.78 or later

  1. Identify the currently installed Novell iPrint Client version on the Windows system
  2. Navigate to the Novell iPrint Client download page or access through the Novell iPrint server
  3. Download Novell iPrint Client version 5.78 or later
  4. Close any applications using iPrint functionality
  5. Run the installer with administrator privileges
  6. Follow the installation wizard prompts to complete the upgrade
  7. Verify the installed version is 5.78 or higher after installation
