    Multiple security vulnerabilities have been discovered in Pillow, a     Python imaging library, which could result in denial of service or the     execution of arbitrary code if malformed files are processed.

    For the stable distribution (trixie), these problems have been fixed in     version 11.1.0-5+deb13u3.

    We recommend that you upgrade your pillow packages.
