Description

This security bulletin contains information about 2 vulnerabilities.

1) Heap-based buffer overflow (CVE-ID: CVE-2017-7867)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to boundary error in utf8TextAccess() function in common/utext.cpp and the utext_moveIndex32* function in International Components for Unicode (ICU) for C/C++ before 2017-02-13. A remote unauthenticated attacker can trigger heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
