Ubuntu 12.04 LTS : icu regression (USN-2522-2)

Critical Nessus Plugin ID 81698

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 been temporarily backed out until the regression is investigated.

We apologize for the inconvenience.

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).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution
