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.");
