Package : icu
Version : 4.8.1.1-12+deb7u7
CVE ID : CVE-2017-7867 CVE-2017-7868

It was discovered that icu, the International Components for Unicode
library, did not correctly validate its input. An attacker could use
this problem to trigger an out-of-bound write through a heap-based
buffer overflow, thus causing a denial of service via application
crash, or potential execution of arbitrary code.

For Debian 7 "Wheezy", these problems have been fixed in version
4.8.1.1-12+deb7u7.

We recommend that you upgrade your icu packages.
