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

  - PHP is an HTML-embedded scripting language. PHP
    attempts to make it easy for developers to write
    dynamically generated web pages. PHP also offers
    built-in database integration for several commercial
    and non-commercial database management systems, so
    writing a database-enabled webpage with PHP is fairly
    simple. The most common use of PHP coding is probably
    as a replacement for CGI scripts. The php package
    contains the module (often referred to as mod_php)
    which adds support for the PHP language to Apache HTTP
    Server.Security Fix(es):Function
    iconv_mime_decode_headers() in PHP versions 7.1.x below
    7.1.30, 7.2.x below 7.2.19 and 7.3.x below 7.3.6 may
    perform out-of-buffer read due to integer overflow when
    parsing MIME headers. This may lead to information
    disclosure or crash.(CVE-2019-11039)When PHP EXIF
    extension is parsing EXIF information from an image,
    e.g. via exif_read_data() function, in PHP versions
    7.1.x below 7.1.30, 7.2.x below 7.2.19 and 7.3.x below
    7.3.6 it is possible to supply it with data what will
    cause it to read past the allocated buffer. This may
    lead to information disclosure or
    crash.(CVE-2019-11040)An issue was discovered in PHP
    7.3.x before 7.3.1. An invalid multibyte string
    supplied as an argument to the mb_split() function in
    ext/mbstring/php_mbregex.c can cause PHP to execute
    memcpy() with a negative argument, which could read and
    write past buffers allocated for the
    data.(CVE-2019-9025)An issue was discovered in PHP 7.x
    before 7.1.27 and 7.3.x before 7.3.3.
    phar_tar_writeheaders_int in ext/phar/tar.c has a
    buffer overflow via a long link value. NOTE: The vendor
    indicates that the link value is used only when an
    archive contains a symlink, which currently cannot
    happen: 'This issue allows theoretical compromise of
    security, but a practical attack is usually
    impossible.'(CVE-2019-9675)

without introducing additional issues.");
