    Package        : jpeg-xl     CVE ID         : CVE-2025-70103

    It was discovered that missing input sanitising in the PNM/PBM parser of     the reference code implementation of the JPEG XL format could result     in denial of service or potentially the execution of arbitrary code if     malformed images are processed.

    For the stable distribution (trixie), this problem has been fixed in     version 0.11.2-0.1~deb13u2.

    We recommend that you upgrade your jpeg-xl packages.
