Gentoo Linux Security Advisory

Title: ICU: Integer overflow (GLSA 202003-15)
Severity: normal
Exploitable: local, remote
Date: 2020-03-15
Bug(s): #710758
ID: 202003-15


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


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

Affected Packages

Package: dev-libs/icu
Vulnerable: < 65.1-r1
Unaffected: >= 65.1-r1
Architectures: All supported architectures


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.


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.


There is no known workaround at this time.


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