Ubuntu Security Notice USN-1348-1
26th January, 2012
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.10
- Ubuntu 10.04 LTS
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.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 11.10:
- libicu44 4.4.2-2ubuntu0.11.10.1
- Ubuntu 11.04:
- libicu44 4.4.2-2ubuntu0.11.04.1
- Ubuntu 10.10:
- libicu42 4.2.1-3ubuntu0.10.10.1
- Ubuntu 10.04 LTS:
- libicu42 4.2.1-3ubuntu0.10.04.1
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.
