SUSE SLES11 Security Update : icu (SUSE-SU-2018:1602-1)

High Nessus Plugin ID 110443

Synopsis

The remote SUSE host is missing one or more security updates.

Description

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.
