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

  - A stack-based buffer overflow when processing chunked,
    encoded HTTP responses was found in wget. By tricking
    an unsuspecting user into connecting to a malicious
    HTTP server, an attacker could exploit this flaw to
    potentially execute arbitrary code.(CVE-2017-13089)

  - A flaw was found in the way Wget handled symbolic
    links. A malicious FTP server could allow Wget running
    in the mirror mode (using the '-m' command line option)
    to write an arbitrary file to a location writable to by
    the user running Wget, possibly leading to code
    execution.(CVE-2014-4877)

  - A cookie injection flaw was found in wget. An attacker
    can create a malicious website which, when accessed,
    overrides cookies belonging to arbitrary
    domains.(CVE-2018-0494)

  - It was found that wget used a file name provided by the
    server for the downloaded file when following a HTTP
    redirect to a FTP server resource. This could cause
    wget to create a file with a different name than
    expected, possibly allowing the server to execute
    arbitrary code on the client.(CVE-2016-4971)

  - A heap-based buffer overflow, when processing chunked
    encoded HTTP responses, was found in wget. By tricking
    an unsuspecting user into connecting to a malicious
    HTTP server, an attacker could exploit this flaw to
    potentially execute arbitrary code.(CVE-2017-13090)

  - Race condition in wget 1.17 and earlier, when used in
    recursive or mirroring mode to download a single file,
    might allow remote servers to bypass intended access
    list restrictions by keeping an HTTP connection
    open.(CVE-2016-7098)
