These security issues were fixed:
- CVE-2014-8147: The resolveImplicitLevels function in common/ubidi.c in
 the Unicode Bidirectional Algorithm implementation in ICU4C in
 International Components for Unicode (ICU) used an integer data type
 that is inconsistent with a header file, which allowed remote attackers
 to cause a denial of service (incorrect malloc followed by invalid free)
 or possibly execute arbitrary code via crafted text (bsc#929629).
- CVE-2014-8146: The resolveImplicitLevels function in common/ubidi.c in
 the Unicode Bidirectional Algorithm implementation in ICU4C in
 International Components for Unicode (ICU) did not properly track
 directionally isolated pieces of text, which allowed remote attackers to
 cause a denial of service (heap-based buffer overflow) or possibly
 execute arbitrary code via crafted text (bsc#929629).");
