"A vulnerability has been found in the International Components for
Unicode (ICU) library :

CVE-2015-4760

It was discovered that ICU Layout Engine was missing multiple boundary
checks. These could lead to buffer overflows and memory corruption. A
specially crafted file could cause an application using ICU to parse
untrusted font files to crash and, possibly, execute arbitrary code.

For the squeeze distribution, these issues have been fixed in version
4.4.1-8+squeeze4 of icu.

We recommend to 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."
