Pillow is a Python imaging library. Versions 10.3.0 through 12.1.1 did not limit the amount of GZIP-compressed data read when decoding a FITS image, making them vulnerable to decompression bomb attacks. A specially crafted FITS file could cause unbounded memory consumption, leading to denial of service (OOM crash or severe performance degradation). If users are unable to immediately upgrade, they should only open specific image formats, excluding FITS, as a workaround.

The remote Redhat Enterprise Linux 8 / 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:27076 advisory.

    Package        : pillow     CVE ID         : CVE-2026-40192

    It was discovered that missing input sanitising in the FITS support of     Pillow, a Python imaging library, could result in denial of service.

    The oldstable distribution (bookworm) is not affected.

    For the stable distribution (trixie), this problem has been fixed in     version 11.1.0-5+deb13u2.

    We recommend that you upgrade your pillow packages.
