SUSE: 2018:1602-1 Important: ICU Denial of Service and Buffer Overflow

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)
