"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)

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
