Vulnerability Details
CVEID: CVE-2007-4770
DESCRIPTION: libicu is vulnerable to a denial of service related to corrupt REStackFrames. By sending a specially-crafted regular expression containing illegal backreference referrals to capture group zero, a local attacker could crash linked applications.
CVSS Base score: 2.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/39938 for the current score.
CVSS Vector: (AV:L/AC:L/Au:N/C:N/I:P/A:N)
CVEID: CVE-2014-7923
DESCRIPTION: Google Chrome could allow a remote attacker to execute arbitrary code on the system, caused by a memory corruption error in ICU. An attacker could exploit this vulnerability using unknown attack vectors to execute arbitrary code on the system.
CVSS Base score: 6.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/100294 for the current score.
CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:P/A:P)
CVEID: CVE-2014-7926
DESCRIPTION: Google Chrome could allow a remote attacker to execute arbitrary code on the system, caused by a memory corruption error in ICU. An attacker could exploit this vulnerability using unknown attack vectors to execute arbitrary code on the system.
CVSS Base score: 6.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/100297 for the current score.
CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:P/A:P)
CVEID: CVE-2014-8146
DESCRIPTION: ICU Project ICU4C library is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by resolveImplicitLevels function of ubidi.c. By sending an overly long string, a local attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
CVSS Base score: 4.4
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/102875 for the current score.
CVSS Vector: (AV:L/AC:M/Au:N/C:P/I:P/A:P)
CVEID: CVE-2014-9654
DESCRIPTION: ICU could allow a remote attacker to execute arbitrary code on the system, caused by improper size limit checks when handling regular expressions. An attacker could exploit this vulnerability using specially crafted data to execute arbitrary code on the system with elevated privileges or cause the application using ICU to crash.
CVSS Base score: 5.6
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/110456 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L)
CVEID: CVE-2015-5922
DESCRIPTION: Multiple unspecified errors in Apple Mac OS X within ICU have an unknown impact and attack vector.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/106838 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N)
CVEID: CVE-2017-15422
DESCRIPTION: Google Chrome could allow a remote attacker to execute arbitrary code on the system, caused by an integer overflow in ICU. By persuading a victim to visit a specially-crafted Web site, a remote attacker could exploit this vulnerability to execute arbitrary code on the system or cause a denial of service.
CVSS Base score: 6.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/136054 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L)

Disclaimer
According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
