icu vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 15.04
  • Ubuntu 14.10
  • Ubuntu 14.04 LTS

Summary

ICU could be made to crash or run programs as your login if it processed specially crafted data.

Software Description

  • icu - International Components for Unicode library

Details

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

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 15.04
libicu52 - 52.1-8ubuntu0.1
Ubuntu 14.10
libicu52 - 52.1-6ubuntu0.3
Ubuntu 14.04 LTS
libicu52 - 52.1-3ubuntu0.3

To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.

In general, a standard system update will make all the necessary changes.
