gifread.c in gif2png, as used in OptiPNG before 0.7.6, allows remote attackers to cause a denial of service (uninitialized memory read) via a crafted GIF file.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - optipng: heap buffer overflow in the bmp_read_rows function (CVE-2016-3981)

  - optipng: heap buffer overflow in the bmp_rle4_fread function (CVE-2016-3982)

  - gifread.c in gif2png, as used in OptiPNG before 0.7.6, allows remote attackers to cause a denial of     service (uninitialized memory read) via a crafted GIF file. (CVE-2015-7802)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

ifread.c in gif2png, as used in OptiPNG before 0.7.6, allows remote attackers to cause a denial of service (uninitialized memory read) via a crafted GIF file.

The bmp_read_rows function in pngxtern/pngxrbmp.c in OptiPNG before 0.7.6 allows remote attackers to cause a denial of service (invalid memory write and crash) via a series of delta escapes in a crafted BMP image.

Heap-based buffer overflow in the bmp_read_rows function in pngxrbmp.c in OptiPNG before 0.7.6 allows remote attackers to cause a denial of service (out-of-bounds read or write access and crash) or possibly execute arbitrary code via a crafted image file.

Off-by-one error in the bmp_rle4_fread function in pngxrbmp.c in OptiPNG before 0.7.6 allows remote attackers to cause a denial of service (out-of-bounds read or write access and crash) or possibly execute arbitrary code via a crafted image file, which triggers a heap-based buffer overflow.

The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-2951-1 advisory.

    Gustavo Grieco discovered that OptiPNG incorrectly handled memory. A remote attacker could use this issue     with a specially crafted image file to cause OptiPNG to crash, resulting in a denial of service.
    (CVE-2015-7801)

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.
