icu regression
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.04 LTS

Summary:

USN-2522-1 introduced a regression in ICU.

Software Description:
- icu: International Components for Unicode library

Details:

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
been temporarily backed out until the regression is investigated.

We apologize for the inconvenience.

Original advisory details:

It was discovered that ICU incorrectly handled memory operations when
processing fonts. 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)
It was discovered that ICU incorrectly handled memory operations when
processing fonts. 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-2014-6585,
CVE-2014-6591)
It was discovered that ICU incorrectly handled memory operations when
processing regular expressions. 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-2014-7923, CVE-2014-7926, CVE-2014-9654)
It was discovered that ICU collator implementation 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-2014-7940)

Update instructions:

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

Ubuntu 12.04 LTS:
libicu48 4.8.1.1-3ubuntu0.4

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