critical Nessus Plugin ID 81698

Language:

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).
