{"id":"SUSE-SU-2018:1401-2","summary":"Security update for icu","details":"icu was updated to fix two security issues.\n\nThese security issues were fixed:\n- CVE-2014-8147: The resolveImplicitLevels function in common/ubidi.c\n  in the Unicode Bidirectional Algorithm implementation in ICU4C in\n  International Components for Unicode (ICU) used an integer data type\n  that is inconsistent with a header file, which allowed remote attackers\n  to cause a denial of service (incorrect malloc followed by invalid free)\n  or possibly execute arbitrary code via crafted text (bsc#929629).\n- CVE-2014-8146: The resolveImplicitLevels function in common/ubidi.c\n  in the Unicode Bidirectional Algorithm implementation in ICU4C in\n  International Components for Unicode (ICU) did not properly track\n  directionally isolated pieces of text, which allowed remote attackers\n  to cause a denial of service (heap-based buffer overflow) or possibly\n  execute arbitrary code via crafted text (bsc#929629).\n- CVE-2016-6293: The uloc_acceptLanguageFromHTTP function in\n  common/uloc.cpp in International Components for Unicode (ICU) for C/C++\n  did not ensure that there is a '\\0' character at the end of a certain\n  temporary array, which allowed remote attackers to cause a denial of\n  service (out-of-bounds read) or possibly have unspecified other impact\n  via a call with a long httpAcceptLanguage argument (bsc#990636).\n- CVE-2017-7868: International Components for Unicode (ICU) for C/C++\n  2017-02-13 has an out-of-bounds write caused by a heap-based buffer\n  overflow related to the utf8TextAccess function in common/utext.cpp and\n  the utext_moveIndex32* function (bsc#1034674)\n- CVE-2017-7867: International Components for Unicode (ICU) for C/C++\n  2017-02-13 has an out-of-bounds write caused by a heap-based buffer\n  overflow related to the utf8TextAccess function in common/utext.cpp and\n  the utext_setNativeIndex* function (bsc#1034678)\n- CVE-2017-14952: Double free in i18n/zonemeta.cpp in International\n  Components for Unicode (ICU) for C/C++ allowed remote attackers to\n  execute arbitrary code via a crafted string, aka a 'redundant UVector\n  entry clean up function call' issue (bnc#1067203)\n- CVE-2017-17484: The ucnv_UTF8FromUTF8 function in ucnv_u8.cpp\n  in International Components for Unicode (ICU) for C/C++ mishandled\n  ucnv_convertEx calls for UTF-8 to UTF-8 conversion, which allowed remote\n  attackers to cause a denial of service (stack-based buffer overflow\n  and application crash) or possibly have unspecified other impact via a\n  crafted string, as demonstrated by ZNC  (bnc#1072193)\n- CVE-2017-15422: An integer overflow in icu during persian calendar\n  date processing could lead to incorrect years shown (bnc#1077999)\n\n","modified":"2026-02-04T02:42:02.223160Z","published":"2018-10-18T12:43:53Z","related":["CVE-2014-8146","CVE-2014-8147","CVE-2016-6293","CVE-2017-14952","CVE-2017-15422","CVE-2017-17484","CVE-2017-7867","CVE-2017-7868"],"upstream":["CVE-2014-8146","CVE-2014-8147","CVE-2016-6293","CVE-2017-14952","CVE-2017-15422","CVE-2017-17484","CVE-2017-7867","CVE-2017-7868"],"references":[{"type":"ADVISORY","url":"https://www.suse.com/support/update/announcement/2018/suse-su-20181401-2/"},{"type":"REPORT","url":"https://bugzilla.suse.com/1034674"},{"type":"REPORT","url":"https://bugzilla.suse.com/1034678"},{"type":"REPORT","url":"https://bugzilla.suse.com/1067203"},{"type":"REPORT","url":"https://bugzilla.suse.com/1072193"},{"type":"REPORT","url":"https://bugzilla.suse.com/1077999"},{"type":"REPORT","url":"https://bugzilla.suse.com/1087932"},{"type":"REPORT","url":"https://bugzilla.suse.com/929629"},{"type":"REPORT","url":"https://bugzilla.suse.com/990636"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2014-8146"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2014-8147"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2016-6293"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2017-14952"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2017-15422"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2017-17484"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2017-7867"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2017-7868"}],"affected":[{"package":{"name":"icu","ecosystem":"SUSE:Linux Enterprise Server 12 SP2-BCL","purl":"pkg:rpm/suse/icu&distro=SUSE%20Linux%20Enterprise%20Server%2012%20SP2-BCL"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"52.1-8.7.1"}]}],"ecosystem_specific":{"binaries":[{"libicu52_1":"52.1-8.7.1","libicu52_1-data":"52.1-8.7.1","libicu-doc":"52.1-8.7.1","libicu52_1-32bit":"52.1-8.7.1"}]},"database_specific":{"source":"https://ftp.suse.com/pub/projects/security/osv/SUSE-SU-2018:1401-2.json"}}],"schema_version":"1.7.3"}
