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

critical Nessus Plugin ID 97720
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

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

Description

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.

Solution

Update the affected packages.
