   An update that fixes 6 vulnerabilities is now available.

Description:

   This update for icu fixes the following issues:

   - CVE-2016-6293: The uloc_acceptLanguageFromHTTP function in
     common/uloc.cpp did 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.
     (bsc#990636)
   - CVE-2017-7868: ICU had 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: ICU had 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 allowed remote
     attackers to execute arbitrary code via a crafted string, aka a
     "redundant UVector entry clean up function call" issue. (bsc#1067203)
   - CVE-2017-17484:The ucnv_UTF8FromUTF8 function in ucnv_u8.cpp mishandled
     ucnv_convertEx calls for UTF-8 to UTF-8 conversion, which allows 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. (bsc#1072193)
   - CVE-2017-15422: An integer overflow in persian calendar calculation was
     fixed, which could show wrong years. (bsc#1077999)
