Packages

  • icu - International Components for Unicode library

Details

It was discovered that ICU contained a race condition affecting multi-
threaded applications. 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. This issue only
affected Ubuntu 12.04 LTS and Ubuntu 12.10. (CVE-2013-0900)

It was discovered that ICU incorrectly handled memory operations. 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. (CVE-2013-2924)

Update instructions

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

Ubuntu 13.04
Ubuntu 12.10
Ubuntu 12.04

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