"According to the versions of the php packages installed, the EulerOS
installation on the remote host is affected by the following
vulnerabilities :

  - An infinite loop vulnerability was found in
    ext/iconv/iconv.c in PHP due to the iconv stream not
    rejecting invalid multibyte sequences. A remote
    attacker could use this vulnerability to hang the php
    process and consume resources.(CVE-2018-10546)

  - gdImageColorMatch in gd_color_match.c in the GD
    Graphics Library (aka LibGD) 2.2.5, as used in the
    imagecolormatch function in PHP before 5.6.40, 7.x
    before 7.1.26, 7.2.x before 7.2.14, and 7.3.x before
    7.3.1, has a heap-based buffer overflow. This can be
    exploited by an attacker who is able to trigger
    imagecolormatch calls with crafted image
    data.(CVE-2019-6977)

Note that Tenable Network Security has extracted the preceding
description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
