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
X.org libXt 1.1.3 and earlier does not check the return value of the XGetWindowProperty function, which allows X servers to trigger use of an uninitialized pointer and memory corruption via vectors related to the (1) ReqCleanup, (2) HandleSelectionEvents, (3) ReqTimedOut, (4) HandleNormal, and (5) HandleSelectionReplies functions.

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

X.org libXt 1.1.3 and earlier fails to check the return value of XGetWindowProperty, leading to use of uninitialized pointers and memory corruption in five specific functions that handle X window events and selections.

MitigationUpgrade libXt to a version newer than 1.1.3 that includes proper XGetWindowProperty return value validation, or apply vendor patches that add error checking before using the returned property data.

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 installed libXt version
    Run 'dpkg -l libxtst6' or 'rpm -q libXt' or check /usr/lib/libXt.so version using 'ldd --version' or inspect the library file directly
    Affected if Version is 1.1.3 or earlier, or matches 1.0.3 through 1.1.2 (any version listed in affected products)
  2. Verify X server is running
    Check for running X process with 'ps aux | grep Xorg' or check display with 'echo $DISPLAY'
    Affected if X server is active and applications use X window properties, since the vulnerable XGetWindowProperty calls occur during X event handling
  3. Confirm libXt is linked by X client applications
    Use 'ldd <application_binary>' to list linked libraries and verify libXt.so is loaded
    Affected if Applications linking against libXt are in use, particularly those handling X selections or window properties
  4. Audit applications using X selections or window properties
    Review application functionality for use of XGetWindowProperty, XSelectInput, or X clipboard/selection APIs - check source code if available or monitor with 'strace' for XGetWindowProperty calls
    Affected if Applications actively query X window properties or handle selections, which triggers the five vulnerable functions in libXt

Environment is affected if libXt version is 1.1.3 or earlier (including 1.0.x through 1.1.2) AND X window applications using property/selection features are running.

From vendor data
Upgrade available Upgrade to a release after 1.1.3
Interim mitigation

Upgrade libXt to a version newer than 1.1.3 that includes proper XGetWindowProperty return value validation, or apply vendor patches that add error checking before using the returned property data.
