medium Tenable Cloud Security Plugin ID 404536

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

 - 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)

 - The GIF decoding function gdImageCreateFromGifCtx in gd_gif_in.c in the GD Graphics Library (aka libgd),
 as used in PHP before 5.6.31 and 7.x before 7.1.7, does not zero colorMap arrays before use. A specially
