Description

It was discovered that ICU incorrectly handled certain calendars. If an application using ICU processed crafted data, a remote attacker could possibly cause it to crash, leading to a denial of service.

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