Double free in i18n/zonemeta.cpp in International Components for Unicode (ICU) for C/C++ through 59.1 allows remote attackers to execute arbitrary code via a crafted string, aka a "redundant UVector entry clean up function call" issue.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Double free in i18n/zonemeta.cpp in International Components for Unicode (ICU) for C/C++ through 59.1     allows remote attackers to execute arbitrary code via a crafted string, aka a redundant UVector entry     clean up function call issue. (CVE-2017-14952)

Note that Nessus relies on the presence of the package as reported by the vendor.

An update of the icu package has been released.

According to the versions of the icu package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - Double free in i18n/zonemeta.cpp in International     Components for Unicode (ICU) for C/C++ through 59.1     allows remote attackers to execute arbitrary code via a     crafted string, aka a 'redundant UVector entry clean up     function call' issue.(CVE-2017-14952)

  - Stack-based buffer overflow in the     ures_getByKeyWithFallback function in     common/uresbund.cpp in International Components for     Unicode (ICU) before 54.1 for C/C++ allows remote     attackers to cause a denial of service or possibly have     unspecified other impact via a crafted     uloc_getDisplayName call.(CVE-2014-9911)

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

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-2017-17484: 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)

According to the version of the icu packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  - The International Components for Unicode (ICU)     libraries provide robust and full-featured Unicode     services on a wide variety of platforms. ICU supports     the most current version of the Unicode standard, and     they provide support for supplementary Unicode     characters (needed for GB 18030 repertoire support). As     computing environments become more heterogeneous,     software portability becomes more important. ICU lets     you produce the same results across all the various     platforms you support, without sacrificing performance.
    It offers great flexibility to extend and customize the     supplied services. Security Fix(es): Stack-based buffer     overflow in the ures_getByKeyWithFallback function in     common/uresbund.cpp in International Components for     Unicode (ICU) before 54.1 for C/C++ allows remote     attackers to cause a denial of service or possibly have     unspecified other impact via a crafted     uloc_getDisplayName call.(CVE-2014-9911)

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-3458-1 advisory.

    It was discovered that ICU incorrectly handled certain inputs. If an application using ICU processed     crafted data, a remote attacker could possibly cause it to crash or potentially execute arbitrary code     with the privileges of the user invoking the program.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
