USN-1348-1: ICU vulnerability

26 January 2012

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



  • icu - International Components for Unicode library


It was discovered that ICU did not properly handle invalid locale data
during Unicode conversion. 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 11.10
Ubuntu 11.04
Ubuntu 10.10
Ubuntu 10.04

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