Detail

Synopsis

An integer overflow flaw in ICU could possibly allow for the execution of arbitrary code.

Background

ICU is a mature, widely used set of C/C++ and Java libraries providing Unicode and Globalization support for software applications.

Description

It was discovered that ICU's UnicodeString::doAppend() function is vulnerable to an integer overflow. Please review the CVE identifiers referenced below for more details.

Impact

A remote attacker could entice a user to process a specially crafted string in an application linked against ICU, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All ICU users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/icu-65.1-r1"
