Updated icu packages fix security vulnerabilities

Updated icu packages fix security vulnerabilities: The Regular Expressions package in International Components for Unicode (ICU) 52 before SVN revision 292944 allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via vectors related to a zero-length quantifier or look-behind expression (CVE-2014-7923, CVE-2014-7926). The collator implementation in i18n/ucol.cpp in International Components for Unicode (ICU) 52 through SVN revision 293126 does not initialize memory for a data structure, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted character sequence (CVE-2014-7940).
