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)");
