Ubuntu Security Notice USN-3227-1
March 13, 2017
icu vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- - Ubuntu 16.10
- - Ubuntu 16.04 LTS
- - Ubuntu 14.04 LTS
- - Ubuntu 12.04 LTS
Summary:
Several security issues were fixed in ICU.
Software Description:
- - icu: International Components for Unicode library
Details:
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.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 16.10:
libicu57 57.1-4ubuntu0.1
Ubuntu 16.04 LTS:
libicu55 55.1-7ubuntu0.1
Ubuntu 14.04 LTS:
libicu52 52.1-3ubuntu0.5
Ubuntu 12.04 LTS:
libicu48 4.8.1.1-3ubuntu0.7
In general, a standard system update will make all the necessary changes.
