"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)
