    Version        : 1.5.0-2+deb11u1
    CVE ID         : CVE-2022-0699


    An issue has been found in shapelib, a library for reading and writing
    ESRI Shapefiles.
    The issue is related to a double free, which results in a crash and a
    denial of service.



    For Debian 11 bullseye, this problem has been fixed in version
    1.5.0-2+deb11u1.

    We recommend that you upgrade your shapelib packages.

    For the detailed security status of shapelib please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/shapelib
