"Brief introduction 

CVE-2014-9911

Michele Spagnuolo discovered a buffer overflow vulnerability which
might allow remote attackers to cause a denial of service or possibly
execute arbitrary code via crafted text.

CVE-2016-7415

A stack-based buffer overflow might allow an attacker with control of
the locale string to perform a denial of service and, possibly,
execute arbitrary code.

For Debian 7 'Wheezy', these problems have been fixed in version
4.8.1.1-12+deb7u6.

We recommend that you upgrade your icu packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
