The TLS protocol 1.2 and earlier, when a DHE_EXPORT ciphersuite is enabled on a server but not on a client, does not properly convey a DHE_EXPORT choice, which allows man-in-the-middle attackers to conduct cipher-downgrade attacks by rewriting a ClientHello with DHE replaced by DHE_EXPORT and then rewriting a ServerHello with DHE_EXPORT replaced by DHE, aka the "Logjam" issue.

CoreText in Apple iOS 8.x through 8.3 allows remote attackers to cause a denial of service (reboot and messaging disruption) via crafted Unicode text that is not properly handled during display truncation in the Notifications feature, as demonstrated by Arabic characters in (1) an SMS message or (2) a WhatsApp message.

The page-loading implementation in WebKit, as used in Apple Safari before 6.2.6, 7.x before 7.1.6, and 8.x before 8.0.6, does not properly handle the rel attribute in an A element, which allows remote attackers to bypass the Same Origin Policy for a link's target, and spoof the user interface, via a crafted web site.

The history implementation in WebKit, as used in Apple Safari before 6.2.6, 7.x before 7.1.6, and 8.x before 8.0.6, allows remote attackers to bypass the Same Origin Policy and read arbitrary files via a crafted web site.

WebKit, as used in Apple Safari before 6.2.6, 7.x before 7.1.6, and 8.x before 8.0.6, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted web site, a different vulnerability than CVE-2015-1152 and CVE-2015-1154.

WebKit, as used in Apple Safari before 6.2.6, 7.x before 7.1.6, and 8.x before 8.0.6, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted web site, a different vulnerability than CVE-2015-1153 and CVE-2015-1154.

The resolveImplicitLevels function in common/ubidi.c in the Unicode Bidirectional Algorithm implementation in ICU4C in International Components for Unicode (ICU) before 55.1 does not properly track directionally isolated pieces of text, which allows remote attackers to cause a denial of service (heap-based buffer overflow) or possibly execute arbitrary code via crafted text.
