    CVE-2021-31535

    Summary: Updated libx11 packages fix a security vulnerability

    Details: XLookupColor() and other X libraries function lack proper validation of the length of their string parameters. If those parameters can be controlled by an external application (for instance a color name that can be emitted via a terminal control sequence) it can lead to the emission of extra X protocol requests to the X server (CVE-2021-31535).
