"icu was updated to fix two security issues. These security issues were
fixed :

  - CVE-2014-8147: The resolveImplicitLevels function in
    common/ubidi.c in the Unicode Bidirectional Algorithm
    implementation in ICU4C in International Components for
    Unicode (ICU) used an integer data type that is
    inconsistent with a header file, which allowed remote
    attackers to cause a denial of service (incorrect malloc
    followed by invalid free) or possibly execute arbitrary
    code via crafted text (bsc#929629).

  - CVE-2014-8146: The resolveImplicitLevels function in
    common/ubidi.c in the Unicode Bidirectional Algorithm
    implementation in ICU4C in International Components for
    Unicode (ICU) did not properly track directionally
    isolated pieces of text, which allowed remote attackers
    to cause a denial of service (heap-based buffer
    overflow) or possibly execute arbitrary code via crafted
    text (bsc#929629).

  - CVE-2016-6293: The uloc_acceptLanguageFromHTTP function
    in common/uloc.cpp in International Components for
    Unicode (ICU) for C/C++ did not ensure that there is a
    '\0' character at the end of a certain temporary array,
    which allowed 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 (bsc#990636).

  - CVE-2017-7868: International Components for Unicode
    (ICU) for C/C++ 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 (bsc#1034674)

  - CVE-2017-7867: International Components for Unicode
    (ICU) for C/C++ 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_setNativeIndex* function (bsc#1034678)

  - CVE-2017-14952: Double free in i18n/zonemeta.cpp in
    International Components for Unicode (ICU) for C/C++
    allowed remote attackers to execute arbitrary code via a
    crafted string, aka a 'redundant UVector entry clean up
    function call' issue (bnc#1067203)

  - CVE-2017-17484: The ucnv_UTF8FromUTF8 function in
    ucnv_u8.cpp in International Components for Unicode
    (ICU) for C/C++ mishandled ucnv_convertEx calls for
    UTF-8 to UTF-8 conversion, which allowed remote
    attackers to cause a denial of service (stack-based
    buffer overflow and application crash) or possibly have
    unspecified other impact via a crafted string, as
    demonstrated by ZNC (bnc#1072193)

  - CVE-2017-15422: An integer overflow in icu during
    persian calendar date processing could lead to incorrect
    years shown (bnc#1077999)

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