Debian Security Advisory DSA 3830-1 (icu - security update)

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.

This check tests the installed software version using the apt package manager.

For the stable distribution (jessie), these problems have been fixed in version 52.1-8+deb8u5. For the upcoming stable (stretch) and unstable (sid) distributions, these problems have been fixed in version 57.1-6. We recommend that you upgrade your icu packages.
