icu was updated to fix two security issues. 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).
Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
