WebKit, as used in Apple iOS before 9.3.2, Safari before 9.1.1, and tvOS before 9.2.1, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted web site, a different vulnerability than CVE-2016-1854, CVE-2016-1856, and CVE-2016-1857.

Security readout for executives and security teams

CVE-2016-1855 is a WebKit memory-corruption flaw. A user on affected Apple software could be compromised, or experience a crash, after visiting a malicious website. The sources identify fixes in iOS 9.3.2, Safari 9.1.1, and tvOS 9.2.1. Exposure is likely limited to legacy systems running iOS before 9.3.2, Safari before 9.1.1, or tvOS before 9.2.1. The WebKitGTK+ reference suggests downstream WebKit relevance, but the supplied bundle does not provide confirmed affected WebKitGTK+ versions. Prioritize remediation where legacy Apple devices still browse the web or process untrusted links. For fully updated fleets, this is mainly a legacy exposure review rather than an emergency response item. Mitigation focus: Upgrade iOS devices to 9.3.2 or later where supported.; Upgrade Safari to 9.1.1 or later where supported.; Upgrade tvOS to 9.2.1 or later where supported..
