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
Use-after-free vulnerability in WebKit in Apple iOS before 4.1 on the iPhone and iPod touch, and webkitgtk before 1.2.6, allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via vectors involving selections.

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

Use-after-free vulnerability in WebKit's selection handling mechanism allows remote attackers to execute arbitrary code or crash applications by freeing memory associated with selection objects then continuing to use those freed memory pointers.

MitigationUpdate Apple iOS to version 4.1 or later, or webkitgtk to version 1.2.6 or later to obtain patched WebKit components.

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 webkitgtk version on Ubuntu
    Run `dpkg -l | grep webkitgtk` or check the package version with `apt-cache policy libwebkit-1.0-0` (or libwebkit-1.2-0) to find the installed version number
    Affected if The installed version is less than 1.2.6
  2. Confirm Ubuntu release version
    Run `lsb_release -r` or check `/etc/lsb-release` to identify the Ubuntu release
    Affected if The system runs Ubuntu 9.10, 10.04, or 10.10 AND uses a WebKit browser with vulnerable webkitgtk libraries
  3. Identify WebKit-based applications
    Check for installed WebKit browsers such as Epiphany, Midori, or other packages that depend on webkitgtk by running `dpkg -l | grep -i webkit` or `apt-cache rdepends libwebkit-1.0-0`
    Affected if A WebKit-based browser or application is installed on an affected Ubuntu release (< 10.04 LTS with webkitgtk < 1.2.6)
  4. Check iOS version on Apple devices
    On iPhone, iPad, or iPod Touch, go to Settings > General > About to view the iOS version number
    Affected if The device runs iOS version lower than 4.1

You are affected if webkitgtk < 1.2.6 is installed on Ubuntu 9.10/10.04/10.10, or if any WebKit-based browser runs against that vulnerable library, or if an iOS device is below version 4.1.
