   An update that fixes 8 vulnerabilities is now available.

Description:

   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)
