im_vips2dz in /libvips/libvips/deprecated/im_vips2dz.c in libvips before 8.8.2 has an uninitialized variable which may cause the leakage of remote server path or stack address.

The remote Ubuntu 16.04 ESM / 18.04 ESM / 22.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6437-1 advisory.

    Ziqiang Gu discovered that VIPS could be made to dereference a NULL

    pointer. If a user or automated system were tricked into processing

    a specially crafted input image file, an attacker could possibly use this issue to cause a denial of     service. This issue only affected

    Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. (CVE-2018-7998)

    It was discovered that VIPS did not properly handle uninitialized memory locations when processing     corrupted input image data. An attacker could

    possibly use this issue to generate output images that expose sensitive

    information. This issue only affected Ubuntu 16.04 LTS

    and Ubuntu 18.04 LTS. (CVE-2019-6976)

    It was discovered that VIPS did not properly manage memory due to an

    uninitialized variable. If a user or automated system were tricked into

    processing a specially crafted output file, an attacker could possibly

    use this issue to expose sensitive information.

    This issue only affected Ubuntu 16.04 LTS and Ubuntu 18.04 LTS.

    (CVE-2020-20739)

    It was discovered that VIPS could be made to divide by zero in multiple

    funcions. If a user or automated system were tricked into processing a

    specially crafted image file, an attacker could possibly use this issue

    to cause a denial of service. This issue only affected Ubuntu 16.04 LTS

    and Ubuntu 18.04 LTS. (CVE-2021-27847)

    It was discovered that VIPS did not properly handle certain input files

    that contained malformed UTF-8 characters. If a user or automated system

    were tricked into processing a specially crafted SVG image file, an

    attacker could possibly use this issue to cause a denial of service.

    This issue only affected Ubuntu 22.04 LTS. (CVE-2023-40032)
