A buffer overflow in International Components for Unicode could result in execution of arbitrary code or Denial of Service.
|Package||dev-libs/icu on all architectures|
|Affected versions||< 49.1.1-r1|
|Unaffected versions||>= 49.1.1-r1|
International Components for Unicode (ICU) is a set of C/C++ and Java libraries providing Unicode and Globalization support for software applications.
An error in the _canonicalize() function in uloc.cpp could cause a stack-based buffer overflow.
A remote attacker could entice a user to open a specially crafted locale representation using 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-49.1.1-r1"
