referenced in the SUSE-SU-2026:23948-1 advisory.

    - CVE-2026-93586: use-after-free in the `ImagesToBlob` method can lead to a process crash (bsc#1281912).
    - CVE-2026-93587: policy bypass in the PCD, CUBE and HALD coders can lead to extra memory allocation and a
    denial of
      service (bsc#1281909).
    - CVE-2026-93588: NULL pointer dereference in the PNM coder can lead to a denial of service (bsc#1281910).
    - CVE-2026-93589: division-by-zero flaw in the FLIF encoder can lead to a denial of service (bsc#1281911).
    - CVE-2026-93590: failure to perform policy checks during buffer allocation for image pixels in the UHDR
    encoder can
      lead to denial of service (bsc#1281913).
