"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."
