Several vulnerabilities were discovered in the International Components for Unicode (ICU) library.

  - CVE-2014-9911     Michele Spagnuolo discovered a buffer overflow     vulnerability which might allow remote attackers to     cause a denial of service or possibly execute arbitrary     code via crafted text.

  - CVE-2015-2632     An integer overflow vulnerability might lead into a     denial of service or disclosure of portion of     application memory if an attacker has control on the     input file.

  - CVE-2015-4844     Buffer overflow vulnerabilities might allow an attacker     with control on the font file to perform a denial of     service or, possibly, execute arbitrary code.

  - CVE-2016-0494     Integer signedness issues were introduced as part of the     CVE-2015-4844 fix.

  - CVE-2016-6293     A buffer overflow might allow an attacker to perform a     denial of service or disclosure of portion of     application memory.

  - CVE-2016-7415     A stack-based buffer overflow might allow an attacker     with control on the locale string to perform a denial of     service and, possibly, execute arbitrary code.

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

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

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.

  - 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.

Brief introduction 

CVE-2014-9911

Michele Spagnuolo discovered a buffer overflow vulnerability which might allow remote attackers to cause a denial of service or possibly execute arbitrary code via crafted text.

CVE-2016-7415

A stack-based buffer overflow might allow an attacker with control of the locale string to perform a denial of service and, possibly, execute arbitrary code.

For Debian 7 'Wheezy', these problems have been fixed in version 4.8.1.1-12+deb7u6.

We recommend that you upgrade your icu packages.

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

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3227-1 advisory.

    It was discovered that ICU incorrectly handled certain memory operations when processing data. 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 these issues but has instead relied only on the application's self-reported version number.

This update for icu fixes the following security issues :

  - Passing a locale string longer than 255 characters to     uloc_getDisplayName() could have caused a buffer     overflow resulting in denial of service or possible code     execution (bsc#1012224, CVE-2014-9911).

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.

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

  - 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)
