WebKit, as used in Apple Safari before 5.0.6, 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 other WebKit CVEs listed in APPLE-SA-2011-07-20-1.

Security readout for executives and security teams

This is an old WebKit memory-corruption flaw in Apple Safari before 5.0.6. A user visiting a maliciously crafted website could experience a browser crash or arbitrary code execution. Business urgency is mainly for legacy systems still running affected Safari/WebKit versions. Exposure is most likely on unmanaged or legacy Apple endpoints running Safari before 5.0.6 and browsing untrusted websites. The bundle does not identify other affected products or current supported platforms. Treat as high priority only where legacy Safari/WebKit remains in use. Modernized fleets with no Safari before 5.0.6 should have low practical exposure, but inventory confirmation matters. Mitigation focus: Upgrade affected Safari installations to 5.0.6 or later per Apple guidance.; Retire or isolate legacy systems that cannot receive browser updates.; Limit untrusted web browsing from any remaining legacy Safari hosts..
