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
Format string vulnerability in the NSRunAlertPanel function in eBay Skype for Mac 1.5.*.79 and earlier allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a malformed Skype URL, as originally reported to involve a null dereference.

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

Format string vulnerability in the NSRunAlertPanel function of eBay Skype for Mac 1.5.*.79 and earlier allows remote attackers to cause denial of service and possibly execute arbitrary code via malformed Skype URLs. The vulnerability stems from improper handling of user-controlled input passed as a format string.

MitigationUpgrade to a supported version of Skype; the affected product (Skype 1.5 for Mac) is obsolete and no longer receives security patches.

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 if Skype is installed on the Mac system
    Check for the presence of the Skype application in /Applications or the user's application folder, or query using system_profiler SPApplicationsDataType
    Affected if Skype application exists on the system
  2. Determine the installed Skype version
    Use the Finder Get Info window on the Skype application, or run 'mdls' on the application bundle to read the kCFBundleVersionKey metadata, or check /Applications/Skype.app/Contents/Info.plist for CFBundleVersion
    Affected if The installed version cannot be determined or is 1.5.0.79 or earlier
  3. Compare the installed version to the affected range
    Review the version number obtained from the application bundle or Info.plist and compare to 1.5.0.79
    Affected if The installed version is 1.5.0.79 or any earlier version (such as 1.5.0.x where x is less than 79, or any 1.4.x version)
  4. Confirm the vulnerable component is present
    The vulnerability is in the NSRunAlertPanel function which processes Skype URLs - this component is present in all versions 1.5.0.79 and earlier
    Affected if The version check confirms 1.5.0.79 or earlier, meaning the vulnerable code path exists in the installed build

A user is affected if Skype is installed and the version number is 1.5.0.79 or any earlier version in the 1.5.x or 1.4.x family.
