  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 ...
