Multiple integer overflows in the (1) pixops_composite_nearest, (2) pixops_composite_color_nearest, and (3) pixops_process functions in pixops/pixops.c in gdk-pixbuf before 2.33.1 allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted image, which triggers a heap-based buffer overflow.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Multiple integer overflows in the (1) pixops_composite_nearest, (2) pixops_composite_color_nearest, and     (3) pixops_process functions in pixops/pixops.c in gdk-pixbuf before 2.33.1 allow remote attackers to     cause a denial of service (application crash) or possibly execute arbitrary code via a crafted image,     which triggers a heap-based buffer overflow. (CVE-2015-8875)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3085-1 advisory.

    It was discovered that the GDK-PixBuf library did not properly handle specially crafted bmp images,     leading to a heap-based buffer overflow. If a user or automated system were tricked into opening a     specially crafted bmp file, a remote attacker could use this flaw to cause GDK-PixBuf to crash, resulting     in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 12.04 LTS and     Ubuntu 14.04 LTS. (CVE-2015-7552)

    It was discovered that the GDK-PixBuf library contained an integer overflow when handling certain images.
    If a user or automated system were tricked into opening a crafted image file, a remote attacker could use     this flaw to cause GDK-PixBuf to crash, resulting in a denial of service, or possibly execute arbitrary     code. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2015-8875)

    Franco Costantini discovered that the GDK-PixBuf library contained an

    out-of-bounds write error when parsing an ico file. If a user or automated system were tricked into     opening a crafted ico file, a remote attacker could use this flaw to cause GDK-PixBuf to crash, resulting     in a denial of service. This issue only affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. (CVE-2016-6352)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Several vulnerabilities have been discovered in gdk-pixbuf, a toolkit for image loading and pixel buffer manipulation. A remote attacker can take advantage of these flaws to cause a denial-of-service against an application using gdk-pixbuf (application crash), or potentially, to execute arbitrary code with the privileges of the user running the application, if a malformed image is opened.
