Ubuntu 12.04 LTS / 14.04 LTS / 16.04 LTS / 16.10 : icu vulnerabilities (USN-3227-1)

Critical Nessus Plugin ID 97720


The remote Ubuntu host is missing one or more security-related patches.


It was discovered that ICU incorrectly handled certain memory operations when processing data. If an application using ICU processed crafted data, a remote attacker could possibly cause it to crash or potentially execute arbitrary code with the privileges of the user invoking the program.

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.


Update the affected packages.
