Security Bulletin


Summary

IBM has addressed the following vulnerabilities in the ICU libraries used by drouter: CVE-2014-8147, CVE-2014-8146, CVE-2017-14952, CVE-2020-10531,

Vulnerability Details

CVEID:   CVE-2014-8147
DESCRIPTION:   ICU Project ICU4C library could allow a local attacker execute arbitrary code on the system, caused by an error in the resolveImplicitLevels function of ubidi.c. By sending an overly long string, an attacker could exploit this vulnerability to 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/102876 for the current score.
CVSS Vector: (AV:L/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-2017-14952
DESCRIPTION:   International Components for Unicode (ICU) for C/C++ could allow a remote attacker to execute arbitrary code on the system, caused by a double free in i18n/zonemeta.cpp. By using a specially crafted string, an attacker could exploit this vulnerability to execute arbitrary code on the system.
CVSS Base score: 9.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/133526 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)

CVEID:   CVE-2020-10531
DESCRIPTION:   International Components for Unicode (ICU) for C/C++ is vulnerable to a heap-based buffer overflow, caused by an integer overflow in UnicodeString::doAppend() function in common/unistr.cpp. By sending a specially-crafted request, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
CVSS Base score: 9.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/177660 for the current score.
