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) This update was imported from the SUSE:SLE-12:Update update project.
