CVE-2011-1059: Use-after-free vulnerability in WebCore in WebKit before r77705, as used in Google Chrome before 11.0.672.2...

Security readout for executives and security teams

CVE-2011-1059 is an old WebKit browser engine memory-safety flaw. A user could be enticed to resubmit a form, causing the browser to crash and possibly leading to unspecified additional impact. The sources name Google Chrome before 11.0.672.2 and WebKit before r77705. Exposure is most plausible in legacy Chrome builds before 11.0.672.2 or products embedding WebKit before r77705. Modern managed browsers are unlikely to be affected, but older kiosks, appliances, or embedded WebKit applications should be checked. Treat this as a legacy exposure cleanup item unless old WebKit-based systems are still in production. It is not KEV-listed in the provided data, but affected browser engines can create operational disruption and uncertain memory-safety risk. Mitigation focus: Upgrade Chrome beyond 11.0.672.2 where relevant.; Ensure embedded WebKit includes r77705 or later fixes.; Retire unsupported legacy browsers and WebKit runtimes..
