Double free vulnerability in the gdImagePngPtr function in libgd2 before 2.2.5 allows remote attackers to cause a denial of service via vectors related to a palette with no colors.

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

  - Double free vulnerability in the gdImagePngPtr function in libgd2 before 2.2.5 allows remote attackers to     cause a denial of service via vectors related to a palette with no colors. (CVE-2017-6362)

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

According to the versions of the gd package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - Integer signedness error in GD Graphics Library 2.1.1     (aka libgd or libgd2) allows remote attackers to cause     a denial of service (crash) or potentially execute     arbitrary code via crafted compressed gd2 data, which     triggers a heap-based buffer overflow.(CVE-2016-3074)

  - The output function in gd_gif_out.c in the GD Graphics     Library (aka libgd) allows remote attackers to cause a     denial of service (out-of-bounds read) via a crafted     image.(CVE-2016-6161)

  - Stack consumption vulnerability in the     gdImageFillToBorder function in gd.c in the GD Graphics     Library (aka libgd) before 2.2.2, as used in PHP before     5.6.28 and 7.x before 7.0.13, allows remote attackers     to cause a denial of service (segmentation violation)     via a crafted imagefilltoborder call that triggers use     of a negative color value.(CVE-2016-9933)

  - Double free vulnerability in the gdImagePngPtr function     in libgd2 before 2.2.5 allows remote attackers to cause     a denial of service via vectors related to a palette     with no colors.(CVE-2017-6362)

According to the versions of the gd package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - Integer overflow in gd_io.c in the GD Graphics Library     (aka libgd) before 2.2.4 allows remote attackers to     have unspecified impact via vectors involving the     number of horizontal and vertical chunks in an     image.(CVE-2016-10168)

  - Double free vulnerability in the gdImagePngPtr function     in libgd2 before 2.2.5 allows remote attackers to cause     a denial of service via vectors related to a palette     with no colors.(CVE-2017-6362)

  - Integer signedness error in GD Graphics Library 2.1.1     (aka libgd or libgd2) allows remote attackers to cause     a denial of service (crash) or potentially execute     arbitrary code via crafted compressed gd2 data, which     triggers a heap-based buffer overflow.(CVE-2016-3074)

  - Stack consumption vulnerability in the     gdImageFillToBorder function in gd.c in the GD Graphics     Library (aka libgd) before 2.2.2, as used in PHP before     5.6.28 and 7.x before 7.0.13, allows remote attackers     to cause a denial of service (segmentation violation)     via a crafted imagefilltoborder call that triggers use     of a negative color value.(CVE-2016-9933)

  - gd_gif_in.c in the GD Graphics Library (aka libgd), as     used in PHP before 5.6.33, 7.0.x before 7.0.27, 7.1.x     before 7.1.13, and 7.2.x before 7.2.1, has an integer     signedness error that leads to an infinite loop via a     crafted GIF file, as demonstrated by a call to the     imagecreatefromgif or imagecreatefromstring PHP     function. This is related to GetCode_ and     gdImageCreateFromGifCtx.(CVE-2018-5711)

  - The gdImageCreateFromGd2Ctx function in gd_gd2.c in the     GD Graphics Library (aka libgd) before 2.2.4 allows     remote attackers to cause a denial of service     (application crash) via a crafted image     file.(CVE-2016-10167)

  - The output function in gd_gif_out.c in the GD Graphics     Library (aka libgd) allows remote attackers to cause a     denial of service (out-of-bounds read) via a crafted     image.(CVE-2016-6161)

libgd developers report :

Double free vulnerability in the gdImagePngPtr function in libgd2 before 2.2.5 allows remote attackers to cause a denial of service via vectors related to a palette with no colors.

A double-free vulnerability was discovered in the gdImagePngPtr() function in libgd2, a library for programmatic graphics creation and manipulation, which may result in denial of service or potentially the execution of arbitrary code if a specially crafted file is processed.

For Debian 7 'Wheezy', these problems have been fixed in version 2.0.36~rc1~dfsg-6.1+deb7u10.

We recommend that you upgrade your libgd2 packages.

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-3410-1 advisory.

    It was discovered that the GD Graphics Library (aka libgd) incorrectly handled certain malformed PNG     images. A remote attacker could use this issue to cause the GD Graphics Library to crash, resulting in a     denial of service, or possibly execute arbitrary code.

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

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