  script_tag(name:"insight", value:"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)");
