Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

USN-2522-1 fixed vulnerabilities in ICU. On Ubuntu 12.04 LTS, the font patches caused a regression when using LibreOffice Calc. The patches have now been updated to fix the regression.

We apologize for the inconvenience.

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. (CVE-2013-1569, CVE-2013-2383, CVE-2013-2384, CVE-2013-2419)
