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

  - Unspecified vulnerability in the Java SE and Java SE
    Embedded components in Oracle Java SE 6u105, 7u91, and
    8u66 and Java SE Embedded 8u65 allows remote attackers
    to affect confidentiality, integrity, and availability
    via unknown vectors related to 2D.(CVE-2016-0494)

  - Unspecified vulnerability in Oracle Java SE 6u101,
    7u85, and 8u60, and Java SE Embedded 8u51, allows
    remote attackers to affect confidentiality, integrity,
    and availability via unknown vectors related to
    2D.(CVE-2015-4844)

  - Stack-based buffer overflow in the Locale class in
    common/locid.cpp in International Components for
    Unicode (ICU) through 57.1 for C/C++ allows remote
    attackers to cause a denial of service (application
    crash) or possibly have unspecified other impact via a
    long locale string.(CVE-2016-7415)

  - The uloc_acceptLanguageFromHTTP function in
    common/uloc.cpp in International Components for Unicode
    (ICU) through 57.1 for C/C++ does not ensure that there
    is a '\0' character at the end of a certain temporary
    array, which allows remote attackers to cause a denial
    of service (out-of-bounds read) or possibly have
    unspecified other impact via a call with a long
    httpAcceptLanguage argument.(CVE-2016-6293)

  - The Regular Expressions package in International
    Components for Unicode (ICU) for C/C++ before
    2014-12-03, as used in Google Chrome before
    40.0.2214.91, calculates certain values without
    ensuring that they can be represented in a 24-bit
    field, which allows remote attackers to cause a denial
    of service (memory corruption) or possibly have
    unspecified other impact via a crafted string, a
    related issue to CVE-2014-7923.(CVE-2014-9654)

  - International Components for Unicode (ICU) for C/C++
    before 2017-02-13 has an out-of-bounds write caused by
    a heap-based buffer overflow related to the
    utf8TextAccess function in common/utext.cpp and the
    utext_moveIndex32* function.(CVE-2017-7868)

  - A vulnerability was found in the International
    Components for Unicode (ICU). Specially crafted invalid
    utf-8 text, when parsed or manipulated using particular
    functions in libicu, could cause out-of-bounds heap
    reads and writes potentially leading to a crash, memory
    disclosure, or possibly code execution.(CVE-2017-7867)

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.");
